The only possible STD that conceivably could cause something like this is molluscum contagiosum. However, I doubt that is what you have. No other STD causes the sort of problem you describe. Whether the problem started with a sebaceous cyst, a simple pimple, or something else, I cannot say. Whatever it is or was, it seems likely that scarring has created the things you now see.
This doesn't sound like anything to worry about. But the only way to know for sure is to see a health care provider in person. No online source will be able to give you a definite answer.
Good luck-- HHH, MD
like I said before hoe ca i help it, do i continue to fight it or just try to let it heal and see what happens.
and like i said before its only one bump, somtimes smaller scabsious cystsill show up but i know that normal, just this one that now keeps me from doing things. I dont think its molluscum contagiosum cause I googled it and the picture dont quite match up..well at all.
Mate, you need to go to a doctor. It does not sound like anything major, but if you continually pick at it you will never find out what it is and could makes things worse - like making it scar.
Vising the doctor is the best option.
