My symptoms, My legs and arms twitching once an while and sometimes I have burning sensation on my back, legs, and arms. I had an EMG done last week and then the next 2 days after that I felt like I had electricity on my arms and legs, which made my index finger shake for practically a day. I received my results for the EMG and it came back normal. I ve also had a lumbar, and head MRI and both came back fine. Basically, they don t know what I have yet, I ve been like this for 2 months now. Thanks, -Ana
