Armpit bumps are small, raised areas on the skin caused by conditions like keratosis pilaris, irritation, or infection. These bumps often appear due to blocked hair follicles, friction, or ingrown hairs.
Several factors can lead to bumps under the arms. The most frequent causes include:
Pay attention to the appearance and symptoms of the bumps. Keratosis pilaris usually appears as small, flesh-colored bumps without pain or itching. Folliculitis may involve redness, swelling, and pus. Razor burn often causes redness and irritation shortly after shaving.
Most armpit bumps are harmless, but consult a doctor if they persist, worsen, or are accompanied by severe pain, swelling, or signs of infection like fever. A dermatologist can diagnose the issue and recommend treatment.
To prevent armpit bumps, avoid tight clothing, use gentle skincare products, and exfoliate regularly. For existing bumps, apply warm compresses, use over-the-counter antifungal or antibacterial creams, and avoid shaving until the skin heals.
