For the last 3 night my right testicle has been extremely sensitive and sore. I went back to work last Monday after a few months off and I sit at a dexk most of the day. The soreness starts in the late afternoon and gets much worse after getting home. I usually sleep nude but during the winter I wear briefs and a tee. The pain radiates from the testicle toward my groin and after about an hour in bed it stops enough to go to sleep. I tried to get a doctor's appointment but he can't see me until next week. Last night the pain was much better which really confuses me. I have talked with a couple of male friends who are about my age, late 50's, and none have had this problem. I don't really have low hangers or huge balls either and haven't experienced any recent trauma. I did start Testosterone treatment in late December but I can't find any evidence of this as a side effect. Anyone able to shead some light on this?
