There is an excellent article in the most recent NMSS magazine MOMENTUM which addresses this. The title is "The nerve dance: Numbness and tingling". Dr. Stephen Krieger, MD, says "Numbness is a loss of the ability to feel, while tingling is an abnormal or unusual sensation. They often go together."

I hope I did the link thing to the article right, if not you can go to www.nationalmssociety.org and read the article (the whole magazine) online.
