I am so sorry for your wife, Anthony. However, all the research I see tells me that moving helps arthritis, if for no other reason than it lubricates those joints, warms them up and both of those help the pain. It’s the getting going that can be so painful, and I can relate. I’ve got arthritis in a few joints myself. Still, if I can get myself going, I can get relief. The best of luck to you both.
