I had a really bad fissure once, but I cant relate to the stomach or adominal problems, but what helped mine heal up was by taking manny hot - warm baths a day, and expecially after a bowel movement. The warm baths do a number of things, they clean the fissure, they promote the healing by increasing blood flow to the area, they hydrate it, and the warm baths also help to cut down on the pain.
