This all began with an antibiotics. I developed horrible side pain which was eventually diagnosed as ibs. off and on after the antibiotics i have had a pinching pain in my penis/groin. The pain is now more constant however at times is better than others. I have had several Urinalysis which have revealed nothing. Could this be related to ibs or could it be prostatis or something? I'm not worried about an std as I am not currently sexually active.
