I have had testicular pain for the last 6 months. It is a constant dull pain that is worse in the evenings and mornings. In late July, I had a chlamydia and gonorrhea test which came back negative. I was prescribed methylphenidate HCl 10 MG tablet twice a day for 15 days on may 5. My testicular pain continued and I was prescribed Meloxicam for two months. The pain decreased when I was on the antibiotics and the meloxicam. However, when I was off both there pain continued. Next I received an ultrasound on my testicles which came back normal. On October 20, I took another chlamydia and gonorrhea test which was also negative. The pain continued and I was prescribed another antibiotic (don’t know the name) on the 3rd of December that I took for 30 days twice a day. Still the pain continued. Two days ago I took another chlamydia and gonorrhea test which was also negative. My doctor is not sure what is going on and neither do I. I’m worried that I am just getting false negatives because I had a false negative for chlamydia 3 years ago, I know it was false b/c my c.f. got tested and she was positive and she had discolored vaginal discharge. I’m worried that I might have an std even though if been told I’m fine. My gf has been a little more leaky the last month and a half , though the leakage is not discolored, and the last month she has been experiencing a small amount of pain during intercourse. Also, one time about a month ago he had brown vaginal discharge, but only once. She has not been tested or treated for std in the last 3 years. What do you think? Should I be worried about an std?
