<s>[INST] Hi, Every now and then I experience a dull pain just behind mt scrotum. It will last up to 20 min and feels very uncomfortable. It also appears to make one go to the toilet and try doing a poo. The pain will persist a little longer but gradually subside. This feeling may occur as little as once eevry 6 month or more. Recently I had 2 episodes within a month. I am 60 years of age and have regular colonoscopies eevry 5 years. All my results so far have been normal. Last Colonoscopy being 3 years ago. Could this be something series? [/INST] Hello really appreciate your concernLooking at your history this could be caused by infection or inflammation of the testis or epididymis, muscle pull following a trauma or varicocoeleSince I can't physically examine you to get more clues so in my opinion you should visit a general surgeon for clinical examination and a color Doppler study if need be. You can take ibuprofen for pain relief and wear scrotal support. Thanks for your question Please feel free to ask for more information I will be happy to help you wish you good health </s>
