I'm having problems with my hands in general. They are weak and I tend to drop things. I don't know if it's the MG or my age. Essential tremors run in my family. I suspect it is the MG. I am a musician and several years ago I started missing notes completely and could not understand why. I think this was the first symptom I had that something was wrong. Since I started Mestinon I don't miss as many but I still get aggravated with the ones I DO miss.
