I'm having this consistent mild pain in my testicle, mostly on the left side. My doctor thought it might be epididymitis and put me on antibiotics, but it's been three weeks and I'm still in pain and feeling uncomfortable. I've had ultrasounds for my scrotum, kidneys, and bladder, and everything seems normal. I also got my testosterone levels checked, and it's at 327 ngdL. Is this a normal situation, or should I be worried about something else going on?
