I have not officially been diagnosed. Waiting on labs. But because of symptoms, the Doctor started me on Mestinon. It seemed to help at first but now it is only helping a little but my periphial Neuropathy and it is getting worse as I take the medication. I can not tell if the medication is really working because when I feel better, is it because of medicine. I think I have a secondary autoimmune disease that causes the neuropathy. I am so frustrated at this process. Does anyone have any insight they can share that may help. Thank you in advance.
