Last night, the inside of my mouth on the left hand side went slightly numb. Not totally, like when you get an injection from the dentist, I could still feel. It started moving along, towards my jaw and then about an hour or two later it had migrated up to my eye socket. Nothing awful, to warrant a 999call, bit still slightly worrying. Facially I look fine, speech and eyesight isn't affected, can raise both hands etc so not a stroke.
This morning it's ever so slightly still there. The far left side of my face almost feels a little cold, like when the dentist injection is just about worn off.
I'll call the GP in the morning, but any advice? Or any idea what could be causing it?
