Hello. I have been treated for chronic prostatitis with sulfamethoxazole. Although the symptoms seem to be diminishing and I feel much better, there is the purple area just inside of my pee hole. It kind of looks like a vein leading to the opening. At the opening there is what seems to be xcess skin being pushed up from the purplish area creating almost like a fat lip on the one side of the hole. Is this a symptom of prostatitis?
