I have been living with couple of bumps on my scrotum for over 3 years.these are grown there like 3-4 together of a sac and very itchy.I thougt these caused for being athletic and of sweating.But i am really worried now. Those pimple shaped sac are sometimes riped and come out a white thing after pushing out.but there it grows again.Very itchy.now i cant barely walk without scratching my scrotum repeatedly
