Gary has NMO for 27+ years. Lots of spinal damage in the neck and chest area. He recently started Rituxan, about 3 weeks ago was his last dose. Now he has started with involuntary legs stretches again. If I touch them, they go crazy and sometimes if he atempts to move after sitting a long time. Is this a type of spasm? Is there a drug that will help curb these stretches?
