For the last couple of months I've been experiencing a 'hot thumb'. Every now and again I have to look down at my hand to heck that my thumb isn't actually touching something hot because that's what it feels like. Not a scalding burning sort of heat - sort of feels like it's pressed against a warm mug of tea. the thumb itself when I touch it with my other hand doesn't feel any warmer than my other fingers.
Just mentioned it DH and he says I should go to the doctor, but I think it's just a confused nerve.
