I'm having bowel movements that cause me to get hot, sweaty, shaky, I can feel my pulse beating in my head. It starts out with constipation for a few days then when this happens it's like I'm having dirrhea but it's not watery like dirrhea it's just a lot of rapid feces rushing out of me. Does anyone have any idea what this could be cause the doctors have no clue what it is. Thank you to anyone and everyone in advance.
