When I eat certain cheeses (especially strong cheddar and old gouda), immediately after swallowing and before it reaches my stomach I get a strange sensation on my upper cheeks.

I feel a tingle and if i go for a second mouthful I get the sensation of sweating and very fine beads of sweat appear.

Why does it happen? Is it a tyramine response? Why is it so localised? - the location reminds me of a picture from an old anatomy textbook that described the position of the sensors on the face responsible for initiating the dive reflex.
