What Does A Cyst In The Groin Area Indicate?

Pardon the lack of anatomic language but I ve noticed a cyst I believe? It s in the crease between my balls and left leg it was about the size of a pea if not a little bigger and a few days after noticing it it had popped and left an obvious crater but upon closer inspection it s not just a crater but a cavity and the hole it left in my skin is roughly the size of the circular part at the end of a safety pen I ve been doing my best to clean it and keep it relatively dry however I can t seem to find any information about the possible condition and I m too humiliated to visit a doctor it s not pushing or bleeding only bleeding small amount when pressure is applied and it looks irritated yet isn t causing pain however it is a bit tender
