Lymphadenopathy: Enlarged tender nodes are a result of their reacting to an inflammatory process in the area from which their drainage comes. In the inguinal region this is either the distal colon or rectum or the pelvis or urinary tract. If you are at risk of stds, get tested or checked by a gynecologist. If you have symptoms of GI disease, see a pcp or GI doctor.

Monitoring Centers: Lymphatic system absorbs/carries things too big to go into the arteries/veins like bacteria eaten by white cells/digested food. Lymph nodes "taste" the lymph everywhere for bad stuff like bacteria/viruses/cancers, etc. When it detects a problem, it alerts the immune system and your body reacts. They enlarge in response to the inflammation they create when they react. They shrink when all is well.
