It is surprising how many times I've heard about that happening from crossing ones legs. It is a very hard habit to break. I am glad it reversed for you. I doubt mine will go away unless we figure out how to stop the demylenting ie, what causing it. There is a new drug that was just approved we may decide to try in Nov. Wish I didn't have to do that but IVIG is no picnic either.
Good luck to you.
