I totally agree with Winterberry. The sitz bath worked for me also. It's a hard road. I tried everything u said your son was on and did. Many unsuccessful. I tried biologic Humira and it never worked. The good news is I have came up with my plan that works best for me. If I stay with it I am ok, if not I am in alot of rectal pain. This site is very helpful. Tomorrow is always a new start.
