Just got back from the doctors office. I have been suffering for years with Irritable Bowel. I have been in pain for two weeks. First non stop diarhea and now constipation. Doctor is sending me to a Gastro Interologist but I can't get in until next Wednesday. I am in a great deal of pain. Doctor told me to begin taking fiber but I am afraid to colon is so irritated. Anyone have a diet that works?
