I had the tingling sensation when I was on topamax. In my hands, feet and the sides of my face. It goes away in about a month then if they up your dosage it comes back for about a week or so. It was not intolerable for me.

Those who know they do not know gain wisdom. Those who pretend they know ramain ignorant. Those who acknowledge their weakness become strong. Those who flaunt their power will lose it. Wisdom and power follow truth above all. For truth is the way of Tao. --from the Tao Te Ching
