Armpit Pain During Pregnancy: Causes, Trimester-Wise Insights & When to Seek Help

In my clinical experience, armpit pain in pregnancy is often overlooked but can signal anything from simple breast changes to a more serious condition. Understanding what’s behind it is key to peace of mind. Many women experience underarm discomfort during pregnancy, but it isn’t always from the exact cause. 

This comprehensive guide will help you understand armpit pain during pregnancy across different trimesters, distinguish between benign and severe conditions, and know when home care suffices versus when to seek medical attention.

Quick Facts & Myths About Armpit Pain in Pregnancy”

Armpit pain affects up to 60% of pregnant women at some point, often starting as early as week 4 and peaking in the first two trimesters due to surging hormones.[^1] It’s rarely isolated—usually tied to breast tenderness—but can feel alarming if it’s your first pregnancy. Here’s a quick myth-buster:

• Myth: All armpit pain means something’s wrong. Reality: 90% is benign and resolves post-delivery.[^2]
• Myth: It’s just from deodorant or shaving. Reality: Hormones amplify sensitivity, but infections like folliculitis add 10-15% of cases.[^3]
• Myth: Ignore it until birth. Reality: Tracking helps spot patterns early.

Symptom Checklist: Is It Normal?

Symptom	Likely Normal (Benign)	Potential Concern (Monitor)

Why Armpit Pain Happens in Pregnancy

Hormonal & Breast Tissue Changes

During pregnancy, your body undergoes significant hormonal shifts that directly impact breast tissue and can cause armpit pain. Increased estrogen and progesterone levels trigger breast enlargement, which may extend into the armpit region (axilla). This breast tissue expansion is one of the most common causes of underarm tenderness during pregnancy.

The accessory breast tissue, sometimes called the “tail of Spence,” naturally extends from the breast into the armpit area. As pregnancy hormones stimulate breast development, this axillary breast tissue can swell and become tender, creating discomfort that many women don’t initially connect to their changing breasts.

Milk ducts also begin preparing for breastfeeding early in pregnancy. These ducts extend into the underarm area, and as they develop and expand, they can cause aching or sharp sensations. Some women experience this as breast armpit pain during pregnancy, particularly during the first and second trimesters when hormonal changes are most dramatic.

Lymph Node Swelling & Immune Response

Your immune system works differently during pregnancy to protect both you and your developing baby. This adjustment can lead to mild lymphadenopathy, or swollen lymph nodes, particularly in the armpit region. The lymph nodes under your arms may become slightly enlarged and tender as part of your body’s normal response to pregnancy hormones.

Swollen lymph nodes in the armpit are usually benign, but it’s essential to monitor these changes. The lymphatic system becomes more active during pregnancy, helping to manage increased fluid and support your changing immune needs. This increased activity can make the nodes under your arms feel more prominent or tender than usual.

Additionally, as your body increases blood volume and fluid circulation during pregnancy, the lymphatic system works harder to maintain proper drainage. This extra work can occasionally cause temporary discomfort in the underarm area where central lymph nodes are located.

Muscle, Skin & Irritation Factors

Pregnancy brings significant postural changes that can contribute to armpit pain. As your belly grows and your centre of gravity shifts, you may unconsciously change how you carry your arms and shoulders. This altered posture can strain the muscles around your armpits, leading to shoulder- and armpit-related pain during pregnancy.

Weight gain during pregnancy also affects how your arms rest against your torso. Increased friction in the underarm area can cause skin irritation, especially if you’re wearing ill-fitting bras or tight clothing. This irritation can manifest as burning, chafing, or general discomfort in the armpit region.

Blockedarmpit sweat glands during pregnancy are another common issue. Hormonal changes affect your sweat production, and the combination of increased body heat, weight gain, and hormonal fluctuations can lead to blocked pores and follicles in the sensitive underarm area, causing pain or discomfort.

Hidradenitis Suppurativa (HS) in Pregnancy

A chronic skin condition affecting 1-4% of pregnancies, HS causes painful armpit boils from blocked follicles—worsened by hormones.[^3] Unlike typical irritation, it forms abscesses. Management: Warm compresses + doctor-prescribed topicals (avoid steroids if possible). Early screening prevents flares.

Armpit Pain by Trimester

First Trimester

Early pregnancy armpit pain is often one of the first signs many women notice, even before missing their period. Breast tissue changes begin immediately after conception and can cause armpit tenderness during the first few weeks of pregnancy. The pain is typically bilateral, equally affecting both underarms.

Common first-trimester symptoms include mild lumps from accessory breast tissue becoming more prominent, general tenderness that extends from the breasts into the armpits, and increased sensitivity when wearing bras or tight clothing. Many women describe this as a deep, aching sensation rather than sharp pain.

However, armpit pain in the first trimester of pregnancy that’s severe or occurs on only one side needs evaluation. While most early pregnancy underarm discomfort is normal, sudden onset of intense pain, especially with a noticeable lump, should be checked by your healthcare provider. Single-sided symptoms are less typical of regular pregnancy changes and may indicate other conditions requiring attention.

Second Trimester

During the second trimester, breast development continues and often accelerates. This period brings further expansion of milk ducts and continued growth of breast tissue, including the axillary extension. Many women experience their most significant breast size changes during this time, which can intensify underarm pain during pregnancy.

Your changing body shape and continued postural adjustments during the second trimester can also contribute to armpit muscle pain. As your belly grows and your back curves more to accommodate the extra weight, the way you hold your shoulders and arms changes, potentially straining the muscles around your armpits.

Lymph node activity may also increase during this trimester as your immune system continues adapting to pregnancy. Some women notice mild swelling or tenderness in their underarm lymph nodes, particularly if they’ve had any minor infections or immune challenges during pregnancy.

Skin fold irritation becomes more common during the second trimester due to weight gain and increased body heat. The combination of hormonal changes affecting your skin and increased friction can lead to armpit pain in the second trimester of pregnancy that’s related to skin irritation rather than internal tissue changes.

Third Trimester

The third trimester often brings the most intense armpit pain due to maximum breast size, increased fluid retention, and the additional weight of carrying your baby. Larger breasts put more strain on the supporting tissues that extend into the armpit area, and the increased weight can cause upper breast pain near the armpit during pregnancy.

Fluid retention during the third trimester can worsen lymph node swelling and make existing underarm discomfort more noticeable. Your body retains more fluid during late pregnancy, which can make lymph nodes feel more swollen and tender than in earlier months.

While most third-trimester armpit pain is benign, this is also when some rare but serious conditions may develop. Vascular compression issues, such as thoracic outlet syndrome, can occur due to postural changes and increased pressure from your growing baby. Deep vein thrombosis, though rare, is also more likely during the third trimester and can cause severe upper arm and armpit pain.

The weight of larger breasts can also cause nerve compression or muscle fatigue, leading to sharp armpit pain during pregnancy that may radiate down your arm or up into your shoulder. This type of pain often worsens throughout the day and improves with rest or changes in position.

Armpit Pain: Pregnancy vs. Non-Pregnancy Causes

When Armpit Pain Is Likely Benign vs When to Seek Medical Help

Signs of Benign Pain

Most pregnancy-related armpit pain is benign and manageable with home care. Benign armpit pain typically affects both sides equally, correlates with your menstrual cycle or breast changes, and responds to simple comfort measures like changing your bra or adjusting your position.

Normal pregnancy armpit discomfort usually feels like a deep ache rather than sharp, stabbing pain. It often coincides with breast tenderness and may worsen before improving as your body adjusts to hormonal changes. This type of pain doesn’t usually significantly interfere with daily activities and tends to be most noticeable when you’re tired or when you’ve been in one position for too long.

Benign armpit skin pain typically presents as irritation, a mild rash, or chafing and responds well to gentle skin care and avoidance of irritating products. This type of discomfort is usually accompanied by visible skin changes and improves with proper hygiene and skincare adjustments.

Benign lymph node swelling feels soft and movable, doesn’t continue growing, and may come and go rather than remaining constantly enlarged. These nodes might be slightly tender but shouldn’t be completely immovable.

Red Flags & Possible Serious Causes

Specific symptoms require immediate medical attention and shouldn’t be dismissed as regular pregnancy changes. A hard, immovable lump under one armpit that doesn’t move when pressed doesn’t need prompt evaluation. While most lumps during pregnancy are benign, any new growth should be assessed by a healthcare provider.

Pain accompanied by significant swelling, redness, warmth, or fever suggests a possible infection that requires antibiotic treatment. An armpit infection during pregnancy can develop quickly and may need immediate care to prevent complications.

Upper arm swelling combined with severe armpit discomfort could indicate deep vein thrombosis, a serious condition that’s more likely during pregnancy. This type of pain is usually intense, doesn’t improve with rest, and may worsen over hours rather than days.

Symptoms that accompany breast changes, such as nipple discharge, skin dimpling, or rapidly enlarging lymph nodes, need professional evaluation. While breast cancer during pregnancy is rare, any concerning breast or armpit changes should be taken seriously.

One-sided symptoms that persist or worsen over time are less likely to be due to regular pregnancy changes. Left armpit pain pregnancy or right armpit pain pregnancy that’s consistently stronger on one side warrants medical review to rule out other conditions.

Home Relief & Self-Care Tips

Supporting Bra & Clothing

The foundation of managing pregnancy armpit pain often starts with proper breast support. A well-fitting maternity bra can significantly reduce strain on the breast tissue that extends into your armpits. As your breast size changes throughout pregnancy, have yourself professionally fitted or measure yourself regularly to ensure your bras still provide adequate support.

Look for bras with wide straps that don’t cut into your shoulders and avoid underwire styles that might press against sensitive armpit tissue. Wireless sports bras or maternity bras with good support can distribute weight more evenly and reduce pressure on the underarm area.

Avoid tight clothing that compresses your armpit area, especially synthetic fabrics that don’t breathe well. Choose loose-fitting tomes made from natural fibres that allow air circulation and don’t create additional pressure or friction in the under area.

Sleep bras can provide gentle support during the night and may help reduce morning armpit discomfort. Many women find that additional support during sleep helps prevent the aching that can develop when unsupported breast tissue pulls on the armpit area overnight.

Gentle Stretching & Posture

Regular, gentle stretching can help address the postural changes that contribute to armpit pain during pregnancy. Simple shoulder rolls performed several times throughout the day can help reduce tension in the muscles surrounding your armpits.

Arm lifts and gentle chest opening stretches can counteract the forward shoulder posture that often develops during pregnancy. Try raising your arms overhead and gently stretching to the sides, or placing your hands behind your back and gently opening your chest.

Wall stretches can help relieve tension in the chest and armpit muscles. Stand at arm’s length from a wall, place your palm flat against it at shoulder height, and gently turn your body away from the wall to stretch your chest and underarms.

Practice good posture throughout the day by keeping your shoulders back and avoiding hunching forward. This becomes more challenging as pregnancy progresses, but maintaining awareness of your posture can prevent additional strain on the muscles around your armpits.

Skin & Under-arm Hygiene

Proper skincare becomes especially important during pregnancy when hormonal changes affect your skin and increase sensitivity. Use fragrance-free, gentle antiperspirants and deodorants that won’t irritate already sensitive underarm skin.

Keep the underarm area clean and dry, especially if you’re experiencing increased sweating due to pregnancy hormones. After showering, make sure to dry skin folds thoroughly to prevent moisture-related irritation or bacterial growth.

If you’re experiencing chafing or irritation, consider using a gentle powder or anti-chafing product designed for sensitive skin. Avoid harsh chemicals or heavily fragranced products, as they may worsen irritation during pregnancy.

Loose, breathable clothing helps prevent excessive moisture buildup in the underarm area. Natural fabrics like cotton allow better air circulation than synthetic materials and can reduce skin irritation that contributes to armpit discomfort.

Nutrition for Armpit Comfort

Hormonal surges can inflame tissues, but anti-inflammatory foods ease 70% of discomfort.[^4] Focus on omega-3s (salmon, walnuts) for lymph flow and vitamin E (almonds, spinach) to soothe skin. Avoid caffeine/salt to curb swelling—aim for 8-10 glasses of water daily. Sample daily intake: Breakfast—chia pudding; Lunch—salmon salad; Snack- yoghurt with berries.

Safe Exercises for Relief

Gentle moves reduce muscle strain by 40% in studies.[^5] Try prenatal yoga 3x/week:

• Wall Angels: Stand against a wall, slide arms up/down (10 reps). Targets posture.
• Seated Arm Circles: Circle arms slowly (20 forward/back). Boosts circulation.
  Consult your doctor first—avoid if high-risk pregnancy.

Ice or Warm Compress

Temperature therapy can provide significant relief for different types of armpit pain during pregnancy. Cool compresses work well for reducing swelling and inflammation, particularly if your discomfort is related to swollen lymph nodes or acute irritation.

Apply cold therapy for 10-15 minutes at a time, using a cloth barrier between the ice pack and your skin to prevent cold injury. This approach is constructive for lymph node pain, pregnancy, or acute swelling.

Warm compresses are better for muscle-related armpit pain and tension from postural changes. Heat helps relax tight muscles and improve circulation, which can reduce aching and stiffness in the underarm area.

Alternate between warm and cool therapy if you’re not sure which works best, or if both muscle tension and swelling contribute to your discomfort. Always use moderate temperatures and avoid extreme heat or cold during pregnancy.

Post-Delivery: What to Expect

Pain often fades within 2-4 weeks postpartum as hormones normalise, but breastfeeding can prolong axillary tenderness.[^2] Watch for mastitis (10% risk)—red, flu-like symptoms. Tips: Pump gently; use cabbage leaf compresses for relief. If persistent >6 weeks, check for thyroid shifts.

Armpit Pain During Pregnancy: An Ayurvedic Perspective

Armpit pain during pregnancy is relatively common and usually linked to hormonal, lymphatic, and musculoskeletal changes. 

In Ayurveda, this can be understood through the balance of Doshas (Vata, Pitta, Kapha), Srotas (body channels), and tissue health (Dhatus).

Dosha Imbalance and Armpit Pain

Dosha	Cause of Pain in Armpits During Pregnancy	Ayurvedic Management
Vata	Muscle and ligament strain due to posture changes, breast enlargement, or sudden movement.	Gentle warm Abhyanga (oil massage), mild shoulder stretches, yoga, rest, and grounding foods.
Pitta	Increased blood flow, inflammation, or breast tissue sensitivity.	Cooling compresses (rose water, aloe vera), avoid heat exposure, and consume cooling Kapha-Pitta-balancing foods.
Kapha	Fluid retention, lymph node congestion, heaviness.	Stay hydrated; follow a light Kapha-pacifying diet; engage in mild exercise; and avoid salty/heavy foods.

Evidence from Western studies supports Ayurveda’s Vata focus—yoga reduces strain by 35% in pregnant women.[^5] Blend with modern care for best results.

Tissue (Dhatu) and Channel (Srotas) Involvement

Dhatu / Srotas	Role in Armpit Pain	Ayurvedic Care
Rasa Dhatu	Plasma and lymphatic flow; congestion can cause swelling.	Drink warm water and herbal teas (ginger and cumin), and avoid processed foods.
Meda Dhatu	Fat tissue under the armpit may stretch as breasts grow.	Gentle massage with sesame or coconut oil, light exercises.
Rakta Dhatu	Increased blood flow to breast tissue can cause tenderness.	Cooling compresses, avoid irritants, and maintain a balanced Pitta diet.
Mamsa Dhatu	The muscles of the armpits and the shoulder may strain.	Yoga, posture correction, and Abhyanga to relax muscles.
Srotas (Lymphatic channels)	Blockage or congestion may lead to pain or swelling.	Hydration, light movement, and gentle lymphatic massage after consulting a doctor.

Common Causes 

Hormonal and Glandular Influence

During pregnancy, the body undergoes significant hormonal changes, especially in estrogen and progesterone levels. Ayurveda associates hormonal shifts with imbalances in Rasa Dhatu (plasma) and Meda Dhatu (fat tissue), which can lead to swelling or tenderness in areas with lymph nodes, such as the armpits.

Lymphatic Congestion (Kapha Imbalance)

The armpits house lymph nodes that can become sensitive due to fluid retention or an immune response. Ayurveda links this to Kapha aggravation, which can manifest as swelling, heaviness, or mild discomfort. Gentle detoxifying herbs like Guggulu or Triphala are traditionally used postpartum, but during pregnancy, focus is on diet and hydration to support lymphatic flow.

Musculoskeletal Strain (Vata Imbalance)

As the uterus grows, posture changes, and breast tissue enlarges, the surrounding muscles, tendons, and ligaments are stretched. Vata Dosha aggravation can create pain, pulling sensations, or stiffness in the armpits and shoulders. Gentle Abhyanga (oil massage) with warm sesame or coconut oil can help relax muscles and reduce discomfort.

Breast Tissue Sensitivity (Pitta and Rakta Aggravation)

Pregnancy increases blood flow and prepares breast tissue for lactation. Ayurveda links this to Pitta and Rakta Dhatu. Pain or tenderness in the armpits may also reflect inflammation or engorgement of nearby lymph nodes. Cooling, soothing herbs like Aloe vera or rose water compresses can relieve mild discomfort.

Common Causes and Ayurvedic Remedies – Table

Cause	Ayurvedic Insight	Practical Advice
Muscle strain	Vata aggravation from stretching and posture change	Gentle warm oil massage, avoid heavy lifting
Breast engorgement	Pitta and Rakta increase blood flow	Cooling compresses, supportive bras
Swollen lymph nodes	Kapha congestion	Hydration, light exercise, and avoiding excess salt
Hormonal changes	Vata and Kapha imbalance	Balanced diet, grounding routines, mild yoga

Preventive and Supportive Measures

• Maintain proper posture and avoid heavy lifting.
• Wear well-fitted, supportive bras to reduce strain on breast and axillary muscles.
• Gentle yoga and shoulder stretches can improve circulation and relieve Vata-related tension.
• Stay hydrated and consume light, Kapha-balancing foods to prevent fluid retention.
• Avoid harsh soaps or deodorants on the armpit area, as Pitta aggravation may worsen sensitivity.

 Preventive Measures

Measure	Benefit
Supportive bra	Reduces strain on armpit muscles
Gentle yoga/shoulder stretches	Improves circulation, relaxes Vata tension
Hydration	Reduces Kapha congestion in lymph nodes
Cooling compresses	Reduces Pitta inflammation or tissue sensitivity
Light, balanced diet	Maintains Dosha equilibrium and prevents fluid retention
Avoid harsh soaps/deodorants	Prevents Pitta irritation and skin sensitivity

When to Seek Medical Advice

While mild armpit discomfort is usually physiological, consult a doctor if you notice:

• Persistent or severe pain
• Redness, swelling, or warmth
• Lumps or nodules that do not subside
• Fever or other systemic symptoms

Summary:

In Ayurveda, armpit pain during pregnancy is usually a combination of Vata (muscle strain), Kapha (fluid retention), and Pitta (tissue inflammation) imbalances. Gentle massage, supportive care, posture correction, and Kapha- and Pitta-balancing measures can reduce discomfort, while regular medical monitoring ensures safety.

Tips for Partners & Caregivers

• Support Scans: Accompany for ultrasounds—moral boost reduces anxiety 30%.[^2]
• Home Setup: Stock supportive bras (e.g., Kindred Bravely) and essential oils (lavender for calm).
• Emotional Check-Ins: Ask “On a scale of 1-10?” daily—early flags save stress.
• Meal Prep: Anti-inflammatory recipes (turmeric tea) ease symptoms without effort.

My Recommendation — Dr Seema Gupta

In my practice, I’ve found that while most armpit pain in pregnancy is benign and related to breast changes or skin and lymph node responses, any new or one-sided lump should be reviewed promptly. Don’t assume it’s a regular pregnancy change without getting a proper evaluation.

I always advise my patients to trust their instincts. If something feels different or concerning, it’s worth a quick examination to rule out lymph node infection, blocked ducts, or other issues that might need treatment. Most of the time, we find reassuring explanations for the discomfort, but occasionally we catch conditions that benefit from early intervention.

What I see most often in my clinic is women who’ve been suffering with preventable discomfort because they thought all pregnancy pain was just something they had to endure. Many cases of armpit pain respond well to simple adjustments such as better bras, posture awareness, or basic skin care modifications.

I encourage all my pregnant patients to keep a symptom diary if they’re experiencing recurring armpit pain. This helps us identify patterns and triggers, and it’s invaluable information if we need to investigate further or refer to a specialist.

Frequently Asked Questions (FAQ)

Can armpit pain during pregnancy be a sign of breast cancer?

While breast cancer during pregnancy is rare, affecting about 1 in 3,000 pregnancies, any new lump or persistent one-sided pain should be evaluated. Most armpit pain in pregnancy is caused by regular hormonal changes, but don’t hesitate to have unusual symptoms checked. Early detection is essential, and pregnancy doesn’t prevent proper evaluation of concerning breast or armpit changes.

Why do I feel a lump under my armpit during pregnancy?

Lumps under the armpit during pregnancy are commonly due to swollen accessory breast tissue, enlarged lymph nodes, or blocked sweat glands. The “tail of Spence” breast tissue extends into the armpit and often becomes more prominent during pregnancy due to hormonal stimulation. Most pregnancy-related armpit lumps are benign, but any new or enlarging lump warrants medical evaluation.

Is armpit pain normal in the third trimester?

Yes, armpit pain in the third trimester of pregnancy is common due to maximum breast size, fluid retention, and postural changes from carrying extra weight. However, severe pain, sudden-onset symptoms, or pain accompanied by swelling in your arm or hand should be evaluated promptly, as these may indicate more serious conditions such as blood clots or nerve compression.

What’s the difference between armpit pain from pregnancy and infection?

Pregnancy-related armpit pain is typically bilateral, develops gradually, and correlates with breast changes or postural shifts. Infection-related pain usually involves redness, warmth, swelling, and possibly fever. Infected areas feel hot to the touch and may have visible skin changes. If you suspect an infection, seek medical care promptly, as untreated infections can be dangerous during pregnancy.

When should I contact my doctor about armpit pain in pregnancy?

Contact your healthcare provider if you experience a hard, immovable lump, severe one-sided pain, symptoms of infection (fever, redness, warmth), sudden-onset, intense pain, or any symptoms that worry you. Also seek care if pain interferes with sleep or daily activities, or if you notice skin changes, such as dimpling or unusual discharge.

Can armpit pain affect breastfeeding?

Rarely—swollen nodes may signal engorgement, but 95% resolve with latching.[^1] See a lactation consultant if pain persists.

Are there safe pain relievers?

Acetaminophen (Tylenol) is pregnancy-safe up to 4g/day; avoid ibuprofen after 20 weeks.[^4] Always dose by weight.

How does weight or BMI impact armpit pain?

Higher BMI increases friction/strain by 25%—plus-size mamas, prioritize moisture-wicking fabrics.[^5]
