I have severe pain in my arms, hands, spastic pain like an insect bite on my legs. My hands feel like they are being held in ice water. I drop things. Can't lay down in any comfortable position except on my belly with my knees tucked under me. I have degenerative disk 3-7 in my neck. I have a nerve test scheduled April 14. I am so painful, I fear I am getting nerve damage. What should I do?
