CommunityMember8584550, Welcome to our club!! I am 10 years younger than you. Staying positive & learning to laugh at ourselves... is a good thing. How long ago did you have C.Difficile? That is hard to deal with all on its own, but with colitis on top. I fight with fructose intolerance (sugar in any form fruits, veggies, milk, whole grains, most artificial "sugars"😉 & an issue with gluten... I have had C.Difficile (4 years ago) & E. coli (about 30 years ago). I have had to resort to... with Dr.s ok.... of taking an anti-diarrhea medication about 1 time a week to once ever 2 weeks. I also have Degenerative disc & joint disease of the spine, stenosis etc. that also causes diarrhea for me. The Mestinon itself can cause diarrhea for many of us. Have you been to see a urologist yet about the urinary issues to make sure something other than MG is not going on?? Is your Dr talking about other long-term treatment for the MG other than prednisone? Mestinon is like an aspirin it just helps symptoms does nothing for the disease itself. Yes, these symptoms can come and go at the drop of a hat. And some days are just hard no matter how positive we try and be we can't always be... But you are not alone!! We are all here for you. Hug & Love to you Donna!! Sally Farrier...Myasthenia-Gravis.com (Team member).
