about a week ago while i was at the ATM a bicyclists "crashed" into me and i hit the bottom edge of the machine at the groin area (just above my penis). the area hurt for a few days (when i would touch it or stretch my legs) although i couldn't see any bruising, then yesterday i noticed that if i pressed a bit harder against it, i could feel a lump of sorts in the middle of the groin area (about a centimetre) above my penis. it's (almost) perfectly round, hard and doesn't seem to move, in a way it feels like it's the pubic bone itself. now i'm not quite sure what it could be, is it there because of the accident or is it a normal feature of the pubic bone and i just never noticed it before.. or perhaps it is something else?
any help would be much appreciated.
