I'd be concerned about this, "... eye dr ... said my eyes were cloudy and swollen." You said it effected only one eye? Did you see an ophthalmologist? (an MD, different from an optometrist.) Did he dilate your pupils and do a slit lamp test? Which part of your eye is swollen?
Sorry for all the questions, but I've had uveitis/iritis numerous times, and also papillitis, which is swelling of the optic nerve. Both situations are very serious, can lead to blindness, and need to be treated. Every time I had the iritis, I had no pain, only "cloudy" vision, like I was looking through a dirty windshield. I always called my ophthalmologist, who would use the slit lamp test, which is the only way to diagnose or confirm uveitis/iritis, and he always prescribed Pred Forte drops, (which need to be tapered like prednisone as you improve.) The one time I had the papillitis, they used a fluorescein angiogram to see it.
I've been on methotrexate and prednisone in the past (among lots of other meds) and I've never heard of MTX causing or contributing to diabetes, only pred. I know of lots of IBD patients who've had successs with MTX. I have Crohn's throughout my colon, and I'm now using Humira every 10 days with success.
You've been through some pretty frustrating situations with your disease. I live in Iowa, too. I guess I've been lucky to have access to decent (not the greatest, but above average) physicians in my community of 60,000. In the past I have made a choice to switch a couple of times, a rheumatologist and a GI doc, when I didn't feel they were giving me proper treatment (plus we didn't see eye-to-eye.) I feel sad that you keep getting the "lemons," and I wish you had more docs to choose from. Hopefully Mayo will keep working with you to find the right combination of meds to get things under control.
I wish you the best of luck!
