Hi, I'm 28 and have been engaged in weight training for the last 5 years, I've been having sharp abdominal pains and lower down toward the groin/anal area also, accompanied by nausea and diarrhea, not only after the workout, but at times I've needed months off my training. It seems to coincide with when I am training intensely, is this common because of overworked abs/abdominal pressure from training, or could there be an underlying problem? thankyou
