I have crohns that gave me many fistulas hooked to my bladder, hip, and large intestine. This took over 25 years to come to a head and then I had a resection becasue I was so constricted I could not go unless I had Amatiza. Anyway, I dont have the typical flares and symptoms I just grow a mass of fistuals all over on the inside. My doc even called it agressive. I am hopeful that It will take another 25 years before I have issues again but I would like not to have to go thru another surgery but I am doubtful that pentasa alone is going to prevent this. I am looking at presenting my doc with the LDN information and see what he thinks. Do you think that this stuff would be helpful to my type of crohns? It looks so promising.
