Yes, I get cramps. I hate using it and even though I've tried it off and on for 2 years I still can't tell if it helps or causes my symptoms to be worse.
Still, I'm going to try again for a couple of weeks. It seems so logical and easy, if they actually will work.
Hydrocortisone enemas, on the other hand, rarely do that to me. Unfortunately I worry about using them too long and causing damage (thinning) to my colon. After all, in the 2 years since my diagnosis, I went from very mild left sided to "considerably worsened" pancolitis. Maybe it's the mesalamines, who knows. The only time I quit using them, after a month or so, I flared horribly.
