Hi there, Ive been for an ultrasound and it confirms I have a lump inside my testicle (left).  My GP believed it was an epididymytis and prescribed Doxycycline.  I have to wait up to two weeks to see a Urologist.  Can you tell me what the possibilities are?  The lump until today was aching and my scrotum felt very tender and heavy.  Im on day 5 of the antibiotics; the pain has gone but the hard lump is still able to be felt on the left side of the testicle...
Welcome to Chat Doctor .1. The possibilities are benign lumps / inflammatory / infections / malignant causes.2. You have said that it's getting better after treatment, so you have better see for few more days and does not relieve, you have to get a biopsy taken from the lump.3. If symptoms still persists you have to see your urologist. Hope it helps you. Wish you a good health. Anything to ask ? Do not hesitate. Thank you.
