what exactly do you mean by "belly pain"?
i have gastritis at times, but that's a burning pain in my stomach.
i've also "pulled" a tendon? muscle? in the lower right of my abdomen that made lifting my leg up while sitting very painful. also going from laying down to being up hurt too since using that muscle to do that too.
hurt it by doing leg lowering exercises to strengthen my inner core.
exercising sure can be dangerous!
is it like one of these? or something else?
