Armpit pain, though often overlooked, can significantly affect daily activities, from lifting objects to simple arm movements. This discomfort in the underarm area may stem from various causes, ranging from minor muscle strains to more serious medical conditions. Understanding the causes, symptoms, treatment options, and prevention strategies for armpit pain is crucial for effective management and relief. This article provides a comprehensive guide to armpit pain, optimized for readers seeking actionable insights to address and prevent this condition.
Armpit Pain
What is Armpit Pain?
Armpit pain refers to discomfort, soreness, or aching in the underarm region, which contains a complex network of muscles, lymph nodes, nerves, blood vessels, and sweat glands. The axilla, as it’s medically known, is a hub for structures like the axillary artery, brachial plexus, and lymph nodes that drain the arm, chest, and upper back. Pain in this area can be localized or radiate to the shoulder, chest, or arm, and may be acute (sudden) or chronic (persistent). Its causes vary widely, making accurate diagnosis and targeted treatment essential.
Common Causes of Armpit Pain
Armpit pain can result from musculoskeletal issues, infections, or systemic conditions. The most common causes include:
Muscle Strain
Overuse or injury to muscles like the pectoralis major, latissimus dorsi, or rotator cuff muscles from activities such as weightlifting, throwing, or repetitive arm movements can cause armpit pain.
Symptoms include soreness, stiffness, and pain worsened by movement.
Lymphadenitis (Swollen Lymph Nodes)
Inflammation of axillary lymph nodes due to infections (bacterial, viral, or fungal), such as a cold, skin infection, or abscess, can cause painful swelling.
In rare cases, swollen lymph nodes may indicate lymphoma or breast cancer, requiring urgent evaluation.
Infections
Hidradenitis Suppurativa: A chronic condition causing painful lumps or abscesses in sweat glands, common in the armpit.
Folliculitis or Boils: Infected hair follicles or sweat glands can lead to localized pain, redness, and pus.
Shingles: A viral infection (herpes zoster) affecting nerves in the armpit, causing burning pain and a rash.
Nerve-Related Issues
Brachial Plexus Injury: Damage to the nerve network in the shoulder and armpit, often from trauma or repetitive strain, can cause sharp or burning pain.
Pinched Nerve: Compression of nerves in the neck or shoulder may radiate pain to the armpit.
Allergic Reactions or Skin Irritation
Contact dermatitis from deodorants, soaps, or shaving can cause itching, redness, and pain in the armpit.
Friction from tight clothing or poor hygiene may also irritate the sensitive skin.
Breast-Related Issues
Pain from breast tissue inflammation (mastitis), cysts, or tumors can radiate to the armpit, especially in women.
Breast cancer may present with armpit pain if it spreads to axillary lymph nodes.
Heart-Related Conditions
Rarely, armpit pain can be a referred symptom of heart issues, such as angina or a heart attack, often accompanied by chest pain, shortness of breath, or arm numbness.
Other Causes
Arthritis: Shoulder arthritis or inflammation may cause referred pain to the armpit.
Cysts or Lipomas: Benign growths in the armpit can press on nerves or tissues, causing discomfort.
Symptoms of Armpit Pain
Symptoms vary depending on the cause but commonly include:

Acupuncture for Armpit Pain in Tokyo
Acupuncture is a TOM practice that involves inserting thin, sterile needles into specific acupoints to restore the flow of vital energy through meridians. In TOM, pain results from Energy stagnation or blood flow disruptions, often triggered by injury, stress, or systemic imbalances. Acupuncture unblocks these pathways, promoting healing and balance. Modern research explains its effects through:
- Endorphin Release: Stimulating natural painkillers to reduce discomfort.
- Improved Circulation: Enhancing nutrient delivery to tissues.
- Nervous System Modulation: Decreasing pain signals to the brain.
- Anti-Inflammatory Effects: Regulating cytokines to reduce swelling.
For armpit pain, acupuncture targets local and distal acupoints to alleviate pain, relax muscles, and address systemic factors, offering a holistic approach to recovery.
How Acupuncture Treats Armpit Pain
Acupuncture addresses armpit pain through multiple mechanisms, tailored to the underlying cause, whether musculoskeletal, lymphatic, or neuropathic. Below are the key ways it supports relief and recovery:
1. Pain Relief
Armpit pain, whether from a strained muscle or inflamed lymph nodes, can be sharp, aching, or burning. Acupuncture stimulates the release of endorphins and serotonin, reducing pain perception. By targeting acupoints near the armpit and along related meridians, it provides immediate and sustained relief, often decreasing the need for pain medications.
2. Reducing Inflammation
Inflammation is common in conditions like lymphadenitis, hidradenitis suppurativa, or muscle strains. Acupuncture promotes anti-inflammatory responses by increasing blood flow and modulating immune activity. This reduces swelling, redness, and tenderness, accelerating recovery.
3. Promoting Tissue Healing
Enhanced circulation from acupuncture delivers oxygen and nutrients to damaged muscles, tendons, or lymph nodes, aiding repair. This is particularly beneficial for strains, minor nerve injuries, or post-infection recovery, helping restore normal function.
4. Relieving Muscle and Nerve Tension
Tight muscles or compressed nerves in the armpit can exacerbate pain and limit mobility. Acupuncture relaxes muscle fibers and modulates nerve activity by activating the parasympathetic nervous system, improving flexibility and reducing neuropathic pain.
5. Addressing Systemic Imbalances
TOM views armpit pain as a sign of disrupted Energy or blood flow, often linked to the heart, lung, or spleen meridians. Acupuncture restores balance by targeting these meridians, supporting overall health and preventing recurrence. This holistic approach is especially useful for chronic or recurrent pain.
Research supports acupuncture’s efficacy for pain conditions relevant to armpit pain:
- A 2018 meta-analysis in The Journal of Pain found acupuncture reduced chronic musculoskeletal pain by 30-50%, with effects lasting up to 12 months.
- A 2020 study in Evidence-Based Complementary and Alternative Medicine showed acupuncture improved pain and function in soft tissue injuries, applicable to armpit muscle strains.
- A 2019 trial in Acupuncture in Medicine demonstrated electroacupuncture’s effectiveness for neuropathic pain, relevant for brachial plexus issues.
While specific studies on armpit pain are limited, these findings align with acupuncture’s mechanisms for musculoskeletal, inflammatory, and nerve-related conditions, supporting its use.
