For the last 3 weeks I have had numbness and cold fingertips in both hands, prior to
that for the last 6 months I have had a numb left big toe. All of these
symptoms are continuously. Tonight it has moved into both my legs, especially
when I cough I get shocked by my own body. Can you tell me what is going on?
