About a month ago, I woke up to my left arm being numb. Since then, I've had numbness in different parts of my body. Arms, legs, face. The numbness comes and goes and sometimes it feels like it is burning. My back also hurts between my two shoulder blades. I don't know if it's my spine or my muscles that hurt since it goes completely across the top of my back. Other symptoms I've had is dizziness and naseau. I'm being refered to a neurologist for an EMG, but I'm completely freaked out about this test. I think they should do an MRI before subjecting me to a EMG. None of the doctors seems to know what's going on but I need answers!!
