For the last three days, i have had diffuse parasthesias. they vary throughout the day, and affect my arms, legs, neck, and face. i do not have any other symptoms. could this be ms?

No, just forget the term MS in your mind.

Not feasible to interpret the significance of your paresthesias, as it would be better to describe your symptoms and avoid a label. Do not know why you are worried about MS, as this would be a dramatically different presentation.
