I spend a lot of my time at work sat down and last week I sat down quickly and trapped my left testicle which, as you would expect, was very painful. The pain susbsided within a few hours and all was forgotten.. Now I have started to notice an uncomfortable pain behind my left testicle and, if I tense the muscles, it hurts as down the space just below and tot he left og by stomach, which I believe is typical with groin strain? I have checked for any lumps, bumps etc and nothing is there and it is a sporadic pain, often vanishes for hours but then can return for hours again. Any suggestions as getting time off work to visit the doctors is a nightmare where I work
