I am 19 years old, About 2months ago my right testical began to swell and harden and since then it has grown about 2/3 times its usual size, at the start it was there was some pain and i was going to my local gp then the pain stopped so i presumed it would of been ok, now where the vas deferens enters my body in region of pubic hair, it has began to swell too, any view on what this might be?
