I have a very extensive family history of Muscular Dystrophy including my mother and I have been experiencing a lot of leg weakness and some numbness on the top of my feet lately. For example I can't get up a step in a pool if there is no handle bar. I went to see a Neurologist and he sent me for a blood test and scheduled me for an EMG. I got a phone call today that my blood test was normal. Can I still have MD if my blood test came back normal? EMG is not scheduled until next Thursday. I'm going a little crazy!! HELP!!!!
