Sometimes I get a mild pulse jerk on the left side of my chest prior to having a bowel movement. The bowel movements are normal, no blood or diareha it does not happen all the time, but bothers me when it does. There are not after effects either, seems when I poop, it goes away. I had a bladder correction surgery 5 yrs ago and as a result have a minor protrusion of my bowl through my vagina, has been monitored and no need for surgery yet.
