I have had mild coming and going pain in my lower abdomen, mainly on the left side along with discomfort under my testicles for the past month or so. I have had blood/piss tests and a CT scan (pelvis & abdomen) and everything came back negative. The pain lingers coming and going and is more intense after i play racquetball. I have been reading about sports hernias and was curious is its possible I have one? or if I would be in more pain and would have known awhile ago?
