ive been visiting aurologist for about two years now with pain in my testicels. tried a number a drungs but noting really worked. he put me on a muscle relaxer with over the counter pain meds. that worked on and i only took them with i felt pain again. this past few days the pain has been getting worse. and today i think ive felt a lump on my right one, then there was blood in my seamen when i masterbated. should i go to the ER, my doctor is outta town so can get a hold of him.
The swelling may be due to some tumor or HY Chat Doctor.  The cause of bleeding might be infection or some injury or even tumor. So, I would suggest you to go for semen analysis and a USG scrotum done first.
