I had radiation January of 2018. The after effect of the radiation on my rectumwas excruciating the dr gave me protofoam and butt cream plus a variety of other things nothing helped it just took months to go away and heal. When I went to see my gastroenterologist I mentioned this and he gave me nifedipine what a life saver. But recently it came back I just wondered if anyone else had had the same problem? Burning and pain when I have a bowel movement. Also I am using the dilator but lately I had to go to a smaller size as it was getting painful to insert.
