crohn's disease
"Imuran seemed fine for the first couple weeks, until I got a fever of 103 degrees. My doctor instructed me to stop taking the Imuran if my temperature reached 103 degrees, so I stopped for a week or so. My temperature returned to normal, so my doctor instructed me to start Imuran again. After one day's dosage I experienced the worst imaginable pain in my whole torso. It turns out the Imuran gave me Pancriatitis. I had to spend 3 days on an IV drip in the hospital and an all liquid diet for a week after."
