Swollen Lymph Nodes: Overview

Swollen lymph nodes, or lymph glands, are a common symptom in infection and disease. The medical term is Lymphadenopathy. There are various different lymph nodes in the neck, underarm, groin, thigh, and other locations. Depending on the condition, there may be multiple lymph nodes swollen (generalized lymphadenopathy) or only a single lymph node enlarged (local lymphadenopathy), such as swollen neck lymph glands, swollen underarm lymph nodes, swollen groin lymph nodes, etc. The most likely cause is some type of infection (e.g. viral, mononucleosis, HIV/AIDS, etc.), or a post-viral syndrome is a possibility. But it could also be a lymphatic disorder (e.g. Lymphoma, Lymphangioma) and there are also various systematic conditions that could be the cause, such as Leukemia, SLE, sarcoidosis, and other diseases.
