[|Human|] 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...
[|AI|]  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.
