I have recently been diagnosed as having MG with MuSK. About 5 months ago I started feeling pain around my right elbow. My PCP diagnosed it as tennis elbow. About 6 weeks ago it progressed to tingling and numbness from my elbow all of the way down into my right hand. Sometimes like when I am shaving, it gets worse and I worry that I might drop my razor. When I had an EEG, they tested that area all the way up to my face and eyes. I am told that I have a pinched nerve around my C4 vertebra. I thought I would ask this community if this is common with MG. I am not really buying a pinched nerve as the cause since this onset coincides with when my MG symptoms began.
