Suggest Treatment For Pain In Groin With Air Bubble Feeling

I was wondering if there was a way to crack your groin,I feel slight pain but it feels like I need to crack almost as if there are bubbles of air in my groin it's sorta strange.I've pulled my groin before and I know it's no where near that.I'm 16 and I play football.I feel like I may have overstretched but I'm not sure what to do to treat it...(R.I.C.E) ...except the "R" can't happen lol.
