I do not feel the pressure of defecation for more than 1 year and I have to strain for it. I also feel a blockage in the rectum area but I have done my colonoscopy and the reports were normal. previously I have the habit of inserting finger during defecation. And my doctor said that you feel blockage due to muscle tightening. And he gave pegred powder but I am using it and it is also not able to clean the stomach and build pressure. Please suggest me some medicine and permanent treatment for it.
