No, I haven't found out. I go back to see the neuro in the neuromuscular clinic the first week of May. But, he did mention Isaac's syndrome which is neuromyotonia. The Neurontin was working for the symptoms pretty good and then it started causing some very, very strange "dreams" I guess I should call them. Being a single parent I was scared to have this happen in the night. I was up every hour with these dreams. The Neurontin worked great for the twitching, cramping and stiffness so I really hope there is something similar I can try that won't have the weird side effects. I am having some pretty bad twitching and spasms the last few days. I may not ever get a treatment, but I think I am handling the symptoms much better lately. I hope the same for you. Leslie
