Not sure if this is the right place to post this but just looking for some advice. First off, I am a fit and fairly healthy 18 year old (190cm 74kg) who plays a lot of sport. My diet isn't amazing but I wouldn't say it is bad. I do drink alcohol but I don't smoke. Since about this time last year I have had a dull ache in the right testicle most prominantly around the part where it joins to the tubes. That part also feels inflamed/swollen but only very slightly. It is not a real pain but more of a constant ache. I got a doctors checkup from 2 separate doctors around March and an ultrasound which all said that nothing was really wrong (so cancer is not an issue). It went away largely for about 6 months but recently came back this week. I have looked around the internet for suggestions and it seems that many people have had this in a similar on and off fashion for quite long periods of time (>10 years) but noone seems to know a certain cure. Any help/advice would be appreciated, as it is a very annoying and persistant ache.
