crohn's disease
"I had Crohn's with a resection 30 years ago and have been mostly in remission since.  Have recently had a bad flare and narrowing at the anastomosis and need to be on medication, but haven't found one that I can handle.  Asacol gave me such serious body aching and fatigue that I could not function.  Pentasa immediately gave me heart palpitations and arrhythmias so I had to discontinue it."
