I am having a great deal of difficulty with one leg. It seems to lose complete power and then regain it at times for no reason . It does not seem to have any connection with medication times or with exertion. It is, however making walking very diffficult for me Does anyone have any similar problems and/or suggestions. My neuro and orthopedist seem to be useless. I just had an EMG and dont seem to have any nerve damage. I sure could use some advice.
