I have pain in right teste. I have had a scrotol sonogram--nothing showed. Urine test and urinalysis--no infection. No STD, I have no swelling. No fever. I have a small inguinal hernia..a surgeon said--it was not the cause of ONE testicle pain. I had a cath study into my urethra-no blocks/no stones. Ultra sound prostate--enlarged but no infection . I DO have reduced semen compared to 2 years ago..but im in my 50;s. I was treated with CIpro and doxycline..it hasnt helped...my urologist is sure I dont have prostate cancer. There is no lump/ or hard area around t/ in the right teste...the right teste does feel funny compared to left/ I have already seen 2 urologists and a gen surgeon. They cant find the cause.
