I also have tingling in toes, feet
and arm and fingers, as well as a crawling itchy
feeling on my scalp. I have had MRI and blood tests to rule out LUPUS and MS. So far everything is o.k. except it seems like I have moderate rheumatoid arthitis, which I guess is not so good, but less frightening than having MS. You say you feel fine, are you fatigued, and feel pain as well as the tingling.
