posted a few times now. I have more updates. for two months now, i have had a pain in behind the right testicle (epididymis). tested for std's three times. Done bacterial cultures three times. all negative or no growth. the main started early june and persists to this day. have done two ultrasounds. I have an 8mm cyst in the right epididymal head. I have a swollen lymph node in the right groin. the doctor thinks it is due to an infection causing the epididymitis. I have taken two weeks of doxy and am now on day 10 of a 14 day cipro 500 perscription. still no change or improvement. actually a bit worse. I now feel pressure all the way from my right lower abdomen (where node is swollen) all the way down to my right inner thigh. feels almost light a tight or pulled muscle. also, my hip joint is sore. feels painful. Not very painful, but enough to notice. Is there something else that can cause this? I'm in my early 30's and fairly healthy. The STD path is not it as tests have come back negative repeatedly. Three doctors have no called this epididymitis. Two have referred to it as possibly viral as opposed to bacterial. I have an appointment with a urologist but it takes a month and a half to get to see him. Anyone have any clue what could be causing the testicle/epididymis pain and also the lump and pain in the groin that they think is a swollen lymph node?
