Dear Don,
Epididymitis (an inflammation of the epididymis and often the testicle) is not always accompanied by a urinary tract infection, but it can sometimes require months of antibiotics and anti-inflammatory drugs to control the pain. It is difficult to give advice without actually examining you myself, but many men who suffer from epididymitis complain of very similar symptoms. Due to the many different pathologies that can cause scrotal pain and a mass, your physician has referred you to a urologist for an expert opinion.
Unfortunately, due to their similar presentation such as scrotal swelling and sensation of fullness, testicular cancer is often first diagnosed as epididymitis. Your history of having undergone a vasectomy in the past also means that a sperm granuloma could be causing your symptoms. Sperm granulomas form when sperm leak from the testicular end of the vas. Sperm granulomas are rarely symptomatic, but in a few individuals may result in a painful lump. Depending on what your urologist finds on his history and physical exam, he may suggest a scrotal ultrasound to help better delineate the nature of your problem. Close follow-up is critical, and any mass that is still present after a prolonged course of antibiotics should raise suspicion. Very sensitive serum markers such as human chorionic gonadotropin (HCG) and alpha-fetoprotein (AFP) are used to help detect testicular cancer. Despite all of our recent technical advances, the treatment of an often baffling disease like epididymitis still requires a great deal of clinical judgment.
