Hi Tkiser,
I am sorry to hear that you have been in pain. I do not think that this has anything to do with alli, but it's best to be sure. It's always best to listen to your doctor's advice. I also recommend that you contact the customer service line at 1-800-671-2554 (M-F 10am - 6pm ET) to report what you are experiencing.
Keep us posted,
Betty Kovacs, MS, RD
