Gretchen is right on target. Tingling is too vague a symptom to use it as a determining factor for a diagnosis. There are too many things that could cause it, from simple nerve compaction to serious metabolic and/or neurological problems. I hope you're keeping track of any new symptoms that might come along, or when the tingling seems worse, or better (are you doing..or not doing..something that might cause it to occur, for example..), and then share that with your doctor when you next have an appointment.
I do have MS. I have had tingling from mid-torso to toes for all the years (25) that I've had MS. It varies in degree and intensity depending on a host of factors, but is always present.
