Underarm pain is a common concern, and it can stem from a variety of issues, ranging from simple skin irritations to more complex underlying conditions. Understanding the potential causes can help you determine the best course of action and when it’s necessary to seek medical advice.
One frequent reason for underarm discomfort is skin irritation. The sensitive skin in your armpits is vulnerable to reactions from various products and activities. Allergic contact dermatitis can develop when your skin comes into contact with irritants like deodorants, antiperspirants, soaps, detergents, and even shaving creams. This type of dermatitis can manifest as redness, pain, itching, and the formation of blisters. If you suspect allergic contact dermatitis, consider switching to hypoallergenic products and ensure you cleanse your underarms thoroughly before and after applying any topical agents.
Beyond allergic reactions, simple irritation from shaving is another common culprit. The act of shaving itself can cause redness, itching, and pain. Furthermore, rubbing, whether from skin-to-skin contact during movement or friction from clothing, can also lead to underarm irritation and discomfort.

Sometimes, underarm pain is associated with bumps. These bumps can be more than just superficial irritation; they might indicate the presence of an abscess or a cyst. An abscess is characterized as a small pocket filled with pus, often resulting from an infection. A cyst, on the other hand, is a sac that can contain fluid, air, or solid material.
A particular type of abscess to be aware of is hidradenitis suppurativa (HS), also known as acne inversa. HS is a chronic skin condition that develops in areas where skin rubs together, such as the armpits. If bumps in your armpit become painful, persistent, or recurring, it’s crucial to consult a doctor for appropriate treatment. Medical intervention might involve antibiotics or other medications like corticosteroids or hormonal therapy to manage HS effectively.

Ingrown hairs can also lead to cyst formation in the underarm area. In the absence of infection signs like increasing pain, redness, or fever, you can initially try home care. Avoid shaving the area to allow the hair to grow out. Applying a warm, moist compress to your armpit several times daily for 10 to 15 minutes can help open skin pores and facilitate the release of the ingrown hair. When resuming shaving, consider using an electric shaver, which is gentler on the skin, or explore depilatory creams as alternatives to traditional razors.
Beyond skin-related issues, autoimmune conditions can also contribute to underarm pain. Conditions like rheumatoid arthritis (RA) and lupus can cause swollen lymph nodes, which can be perceived as pain or discomfort in the underarm region. Other autoimmune diseases such as adult-onset Still’s disease (AOSD), autoimmune lymphoproliferative syndrome (ALPS), and Kikuchi-Fujimoto disease are also associated with swollen lymph nodes. If you experience persistent underarm pain accompanied by other symptoms like fatigue, fever, or joint pain, it’s important to discuss these concerns with your healthcare provider to rule out underlying autoimmune conditions.
In conclusion, underarm pain can arise from a wide range of causes, from everyday skin irritations to more significant medical conditions. Paying attention to accompanying symptoms and seeking professional medical advice when pain is persistent, severe, or accompanied by other concerning signs is essential for proper diagnosis and management.
