Hey guys, 21 year old male here. Well recently I found a grain of rice sized 'lump' on top of my left testicle. Now it doesn't cause me pain unless I fidget with it for a long period of time, where it causes a sharp shooting pain. I'm a bad hyperchrondriac so I worry about everything I went to the doctors earlier this week, he had a feel around my testicles and told me that everything was fine and that it was just a cyst and that I'd have it for the rest of my life most likely. He got some information up on his computer and said that it was something to do with the epedermus but nothing to worry about and that it 'definitely wasn't cancerous as my testicles are smooth, and he can't find anything wrong and that if he thought anything was bad, hed be sending me for a scan' Problem is that I'm still worrying now like almost a week later, the 'grain' is still there and I can't stop fidgeting with it and worrying. What should I do?
