I had a vaginal hysterectomy 4-1/2 weeks ago with no complications (except a slight belly button infection), but now I have a sharp pain (on and off) in my left abdomen, slight above the belly button and 2 to the left, that comes and goes but is uncomfortable. No bleeding, but could I have done something while exercising like split a stitch or ?? I have been working out mildly for about a week now, mostly walking and some stretching.
