I have been experiencing nerve spasms especially at night. They were set off by a car accident in January. I do have degenerative disc disease and a spinal fusion at C5-C6 about 10 years ago. I also have a skin rash -- which may or may not be related -- for several years on my right hand, calves, and lower arms. Dermatological creams don't work. I have just taken a nerve conductivity test on my arms and legs. I am awaiting the results. Any thoughts?
