I am a 23 year old male PT grad student, sorta poor diet, 5'11 160lbs. I recently discovered a pimple-like ordeal bump under i my gooch area. I had popped it and then as days passed by it has just gotten bigger. It is now the size of a walnut. My father died of cancer and my mother is a breast cancer survivor. For the past few years one of my testicles( smaller than the other, but not by much) has become noticeably more sensitive as well. I have seen a doctor about the testicle pain but he had told me previously that it is nothing to worry about. However this pimple like infection is new (4 days) and has just gotten bigger and i have noticed not only more swelling but another one is coming up. I do not shave so I do not believe that it is an ingrown hair infection.
