Yep, I get it too! For me it's pushing way to hard up a hill and breathing, or trying to breath, with my mouth wide open. You said a "graze" at the back of the throat, that's the perfect description! The last time it happened I cough for about 10 minutes straight at the top of a hill. It was a hard make you gag and pee in your pants type cough! No amount of water will soothe it and for me it lasts a good 24 hours. I'll try some of the cures mentioned next time.

Glad to have a name to put with it. Makes me feel better that it's not just because I'm out of shape. Bikerhen
