Adenitis is a medical term used to describe inflammation or swelling of one or more lymph nodes. Lymph nodes are small, bean-shaped glands located throughout the body that are part of the immune system. They filter lymph fluid as it flows through the body, trapping and destroying harmful substances like bacteria, viruses, and cancer cells.
Adenitis can occur in any part of the body where there are lymph nodes, but it most commonly affects the lymph nodes in the neck, armpits, and groin. The condition can be caused by a variety of factors, including bacterial or viral infections, autoimmune disorders, and cancer.
Symptoms of adenitis include swelling, tenderness, redness, and warmth around the affected lymph nodes. In some cases, the skin over the nodes may become dimpled or appear to be “pulled in.” Other symptoms may include fever, fatigue, and general malaise.
Treatment for adenitis depends on the underlying cause of the condition. In many cases, the condition will resolve on its own as the body fights off the infection or inflammation. Over-the-counter pain relievers like acetaminophen or ibuprofen may help to reduce pain and fever. In more severe cases, prescription medications like antibiotics or steroids may be needed. In rare cases, surgery may be necessary to remove an affected lymph node.
