Does hidradenitis suppurativa cause painful armpit lumps?

Hidradenitis suppurativa begins around hair follicles in areas where skin touches skin, such as the armpits. A lump may feel deep, sore, and swollen rather than like a surface pimple. Episodes can return in the same region, and nearby lumps may join under the skin. Some lesions open and drain; healing can leave thickened skin or scars. Painful armpit lumps have other possible causes, including an inflamed follicle, a boil, or a swollen lymph node, so an examination is needed for diagnosis.

Use a warm, clean compress if it feels soothing, and keep the area gently washed and dry. Choose loose clothing to reduce rubbing. Do not squeeze, pierce, or repeatedly shave over a lump; these actions can injure the skin and worsen inflammation. Note when flares occur, how long they last, whether they drain, and whether they leave marks. A dermatologist can discuss treatments that reduce active inflammation and help prevent new lesions.

Book a medical assessment for recurring, draining, enlarging, or activity-limiting armpit lumps. Seek prompt care if pain escalates quickly, the surrounding redness spreads, the area becomes very hot, or you develop fever or feel unwell. Urgent assessment is appropriate for severe swelling or rapidly worsening symptoms. Early review can help distinguish hidradenitis suppurativa from an abscess or another problem and can limit avoidable scarring.

Ask whether the location, recurrence, drainage, and scarring fit hidradenitis suppurativa, what skin-care changes may reduce friction, and whether you need a dermatology referral. Share any medicines, shaving practices, previous episodes, and family history of similar lumps.
