Okay, well I am only a teen, I don't have diabetes. But, diabetes does affect your sugars, and I am taking that you mean MS as in Multiple Sclerosis. MS does attack the CNS, not the pancreas. Multiple sclerosis should not make it harder to control your sugar levels, your MS medicines may. Immunosuppressants can cause sugar levels to spiral sometimes, yet this medicine can help with both diseases. You may have a third-hand problem going on. You may need to switch meds.
I have absolutely no experience with the diabetes side of this but I know if you have IV solumedrol for a flair, that can play havoc with your sugar levels.
I hope someone else will help out here - anyone??
