I've been referred for EMG/NCS due to weakness in my right leg & drop foot but I'm not sure I want to go ahead with the tests as I don't know exactly what they show and how helpful they will be. I've had discectomy L5S1 but been told this doesn't explain weakness in whole leg and loss of sensation in calf.
I've read up on the tests, but I'm not sure I fully understand what they can/can't show. Do they distinguish between damage to the nerves and spinal cord? If so, can they tell how much damage there is and the extent to which this should affect strength in your leg/sensation/pain?
I'm guessing that even if they do say if there is damage, they can't give an indication of how this was sustained especially if an MRI shows no compression of the nerve roots. I'm wondering what will happen if they come back normal or if they show minimal damage which doesn't correlate to the problems I'm having.
