Chronic lymphadenitis is inflammation or infection of a lymph node for an extended time. Lymph nodes are part of the immune system. This system fights and prevents infections. The lymph node’s job is to filter out unwanted substances, such as bacteria and viruses, and help eliminate them from the body.
Lymph nodes occur in clusters in the neck, armpits, and groin. Chronic lymphadenitis may affect one node, several nodes in one area, or nodes in many areas of the body.
The sooner chronic lymphadenitis is treated, the more favorable the outcome, depending on the cause. If you suspect you have this condition, contact your doctor right away.
