I am having muscle spasms in my arms and legs, and also in my feet and hands. What can I do? I am taking a muscle relaxer, but it helps for only a short time. I try to move around as much as possible, and I still can do some housework, just slowly. I also get in a tub (with lukewarm water) that has the therapy jets almost daily. These are new symptoms for me, and I'm wondering how long they will last and if there is anything else I can do to ease them.
