Wyo,

You said "body, spirit, mind and sometimes heart".
Yes, ALL of those can, and sometimes/often are, symptoms of MS that are directly traceable to the demyelinating actions of the disease within the brain and central nervous system. Check out the film Hilary and Jackie for what I thought was a subtle depiction of what the disease can do even long before one knows diagnostically that they might have, and then actually do have, this malady. It might make the actions of some of our own relatiives and friends more understandable.
