I have irregularly frequent pain in the scrotum. I can feel a slightly hard and painful mass over the testis around the epididymal area. Left mass is smaller and softer. Sometimes the mass turns really hard and painful. I have seen a ufologist and got a plain ultrasound done. He diagnosed it as an epididymis cyst and gave me the appropriate antibiotics. The pain was relieved, in the sense it is still felt but isn't as severe as before. I wanted to make sure that it's not related to prostate cancer as I sometimes have sharp pains which feel like radiating from the prostate. Or when my rectum is full before defecating, it's just uneasy. I have talked this to the urologist, but he talked it off saying prostate cancer isn't probable at this age which I know is true. But still have doubts about it. And I guess being paranoid about this affecting my fertility is lame, but I want to make sure that this doesn't affect.
