OK, I noticed my right nut hurst the day after a sports game. It was also the same day my lower ab was strained but since then, my ab seems to feel better but my right nut hurts. This was on day 19 of cycle currently on day 22. Running 50 mg/day. Prolly will get checked this week if it keeps up, also got scared I had a lump, but I think was just the epididymis, either way nut hurts, wondering if anyone ekse has had this problem
