My Rheumy gave me muscle relaxers for my Fibro, but I have never been given a muscle relaxer for my Crohns. Many of us take things like Vicodin, Ultram, Percoset for our pain. I think your PCP is being a little too over cautious. I have been taking a pain medication daily for years because of the joint related pains of Crohns.
Been living with Crohn's Disease for 32 years. Currently on Asacol, Prilosec 60 mg, Estrace, Prinivil, Diltiazem, Percoset prn for pain and Calcium. Resections in 2002 and 2005. Recently diagnosed with Fibromyalgia and doing tests to see if I have Inflammatory Arthritis or AS.
