Hi. Is it possible to have myasthenia gravis and not have eye or breathing problems? My neurologist started me on mestinon to help with my arm and leg fatigue/weakness. I have been diagnosed with peripheral neuropathy. The mestinon has been like a miracle for me. I have been increasing it every three days and am now on 60mg four times a day. I am wondering if this means i have m.g . Or if it helps with neuropathy problems.
