Hello, I'm a 20 yr old male with recurring testicle pain. I've gone to my GP several times and seen a urologist about 3-4 times and the pain persists. It all started one day after going to the gym, felt like some urine flowed backwards while lifting heavy. Went to my GP, got tested for std but came back negative so they gave me a shot in the rear and put me on doxy for 2 weeks and I felt better. About 3 months later pain came back, might have been because of gym again. During this time I was having sex with a female friend but always used protection. Went again to GP they recommended a ultrasound and then sent me to urologist and the urologist just gave me doxyc and a strong pain med, ended up going to hospital from chest pain due to pain med. Pain persisted and after several doses of doxyc the pain is still there. Sorry for the long post but if anyone could help I would greatly appreciate it. Thanks !
