I thought this was a common and normal reaction to cold food/drinks, though i do find i can eat a large amount of
ice cream and nothing happens
and other times i only get through the 2nd spoon
and my throat and brain are screaming ahhhhhhhhhhhhhhhhhhhh.
I do know a trick that makes the ahhhh pain go quicker, all you do is put your tongue upto the roof of your mouth, push and hold until it stops, it should only take a few seconds.
cheers......
