Julie, numbness is a sensory symptom. It can come and go or stay. there's not alot that can be done for numbness except steroids which may or may not help.

As for getting a diagnosis - unfortunately, symptoms alone won't get you a diagnosis. You need some positive test results and abnormilties on a neuro exam. I don't know if you have had either of those but if not you might be in limbo for awhile.....sorry
