question: I have a tickling and small pinching feelings on left side of face. Like as if its being eaten by small insects or so. It goes away for like an hour once I take panadol then it comes back. I can t touch my face, when I do as if the skin is so thin. May it be something serious? Or just a coming cold maybe? Because also when I drink cold water the left side of my teeth hurt just a bit. What could be possibly causing this? Thanks.
