Hi I as well have had the sameproblems! I aalso have fibro and recently have been diagnosed with RA. I have been so miserable tge last 2 weeks and nothing helps! Mine even goes all around to my back and more pain in tbe left! I found this looking for undigested Topamax in the stool! Gross I now! SORRY! I go to my Rheumatologist Thursday hopefully he can give me some insight or I am going to pull my hair out!
I would see a gastro if you are not already. Also, please add a good, acidophilus supplement to your diet along with a good digestive aid, you can find these at a local health food store, both should help the problems you are having. Oh, and you might want to ask for a food allergy test, food allergies can cause the problems you are having as well.
Are you working with a Gastro Dr? If not you may want to see one. You might want to be tested for food allergies too. I know you said you've cut out certain foods but you may be missing something. You may need to change your medication, up the dose or add another med to it. Only your Dr can tell you that though. Remar
