Hey Kendra,
Sorry you are going through this. I know how scary and frustrating is can be. It could be you just need to reduce your mestinon per your neuro, but I think you should have some lab work done and see your doctor to rule out any other problems. It's always better to be safe than sorry...right? Just so you know, I get those twitches too. Take care and let us know how you make out.
Hugs,
Pat
