Recently i have been having some kind of gentle pain in my right testicle. It becomes very sensetive and just touching it causes pain. Walking becomes hard, as it causes my right testicle to hurt. This comes and goes, iv not had it for a good 6 months, but last night at work it started and when ever i walked it would cause pain to shoot in my right testicle and if i touched it, it would hurt more. When i sit down and relax it goes away after about 30 mins. What is this?
