I get this too, bit its like a buzzing almost in little spots about the size of a nickel. It tinglea, or buzzes im not sure but I get it around my lips, under my nose or on the side of it, cheek and sometimes temples or top of head. I get it when my anxiety is sky high, or when Im not too anxious, it really scared me at first, until I realized it would go away if I kept busy, and after some months it hasnt gotten worse just better. I think as soon as it comes on, you say to yourself " oh its just another weird symptom of anxiety" and stay calm and accept that it is a symptom of anxiety it will get better! Easier said than done though I know.
