My Husband had a colon reconstruction due to a perforation when having a colonoscopy. His reconstruction surgery was 3 weeks ago. For 6 months, his sphincter muscle and anus was sleeping . The surgery went well, but he has extreme pain at the anus opening. He has bowel movements semi solid and then he has multiple bowel movements following, which become looser. Is it possible bile is causing this irritation. He literally screams and its like his bowel or sphincter muscle wants to continually push. What is going on and is this really normal?
