Bumps on the armpit are small, raised areas of skin that can vary in size and texture. These bumps can result from various causes, ranging from benign to more serious conditions. Common causes include ingrown hairs, which occur when hair grows back into the skin instead of out of the follicle, leading to inflammation and small, painful bumps. Another frequent cause is folliculitis, an infection or inflammation of the hair follicles that can produce red, pus-filled bumps. Additionally, armpit bumps can be a result of clogged sweat glands, forming small, sometimes painful lumps known as hidradenitis suppurativa. Lymphadenopathy, or swollen lymph nodes, can also cause lumps in the armpit area, often due to infections or other medical conditions. Sometimes, benign growths like sebaceous cysts or lipomas, which are fatty lumps, can appear in the armpit.
Treatment for bumps on the armpit depends on the underlying cause. For ingrown hairs or folliculitis, maintaining good hygiene and using warm compresses can help soothe the area and promote healing. Topical antibiotics or antiseptic creams may be prescribed if there is an infection. In cases of clogged sweat glands or hidradenitis suppurativa, avoiding irritants and wearing loose-fitting clothing can reduce friction and prevent flare-ups. Treatment may also include medications to reduce inflammation or antibiotics for infections. If the bumps are due to swollen lymph nodes, addressing the underlying infection or condition causing the swelling is essential. For persistent or concerning bumps, especially if they are hard, growing, or associated with other symptoms, consulting a healthcare provider for a thorough evaluation and appropriate treatment is important.
