From a practical standpoint, managing a swollen armpit gland involves both immediate care and long-term strategy. For a simple, uninfected nodule, the treatment is gentle: warm, moist compresses several times a day to encourage drainage, over-the-counter anti-inflammatory medication for pain, and a break from shaving or using harsh antiperspirants. However, if the swelling is accompanied by spreading redness, fever, or chills, or if it recurs in the same spot, medical attention is necessary. A physician may need to lance and drain an abscess or prescribe antibiotics for a secondary infection. For those with chronic HS, treatment is more complex, involving prescription antibiotics, biologic drugs that calm the immune system, laser hair removal, or even surgical excision of the affected sweat glands.
