Does anyone know of possible causes for a tingling face – hard to describe, but I'd say it's like mild pins and needles. It's mostly on the left-hand side of my face, particularly around my eye. (No visible sign, so it's not one of those muscle spasms that makes your eyelid flicker!) I've had similar tingling before, nearer my mouth, but while that has never lasted long, this seems to have gone on for about a week.
Thanks for any insights!
