What Causes Numbness In The Left Hand?

I am losing nerve support in my left hand.Doctor says my MRI s for brain, cervical spine and spine are all normal. EMG test shows no pinched nerves but indicate elevated response in nerves. Two blood tests show slightly elevated levels in muscle something? He s now talking about motor neuron disease and that does not sound encouraging. Just trying to find some info about this.

Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice.

Your symptoms could be related to motor neuron disease, especially if EMG results are suggestive for such disorder and all the other tests are normal.

There is no other special test to diagnose this disorder.

Anyway, I would recommend checking also vitamin B12 plasma levels in order to exclude possible deficiency.

Hope to have been helpful!
