I have a not vissible but can be felt lump in my groin region , i recently had a ringworm is it related?should i take any antibiotics?is it dangerous?

Could be/likely not: The lump is most likely your inguinal lymph nodes.These are part of your immune system that sift through your body serum and remove random debris.They are pea sized at rest and enlarge when working.Cleaning your serum after a ringworm,bug bites, etc.are common reasons they become noticed.They git bigger for a while and return to smaller size over a 3-4 week period.Pain, redness, would need an exam
