What could cause swelling in lymph nodes in groin?

See your doctor: Many things can cause swelling in the lymph nodes, or lymphadenopathy. It can be as simple as a localized infection to a much more serious problem. It needs to be investigated and you need to get some blood tests and possibly a biopsy of the lymph nodes if nothing else is found to be causing it.

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.
