I was doing it again today -- watching the Dr. Oz TV program. He took a question from a woman who wanted to know about "pins and needles" in her feet. He answered that there are two possible sources for this problem: inadequate blood supply or a problem with nerves.
The question and answer are seen here, about 3:45 into the video: http://www.doctoroz.com/videos/tv-docs-need-dr-oz-pt-2
Once again I doubt that MS is fundamentally a neurological problem. Decades in the jurisdiction of neurology have made little progress, in my opinion; perhaps investigation into the bloodstream (and substances traveling there -- like insulin, for example) may bring us real results.
