Does anyone have these symptoms? After a bad spasm and a shot of bentyl and demerol, 2 days of quiet then 7 days of internal vibrations with heat front and back in the abdomin. Sort of like a hot flash or niacin flush. It hasn't stopped but changes in intensity. Along with it is a symptom I've never had before - diarrhea, a yellow brown color. Sound familiar to anyone? Help! I'm new at this.
