I Am Regularly (sometimes 2 Or 3 Times A Day)

I am regularly (sometimes 2 or 3 times a day) having pins & needles running upwards from my feet to my neck & at the same time from my hands up to my neck. I have a constant headache. I am about to see a specialist as it is suspected that I may have the start of Motor Neuron Disease following a Ultrasound for an unrelated throat problem. Could this be caused by MND or possibly something else?
