Crazy question

When i sprint (like suicide drills, shuttle runs, 200 m dash), my face/mouth goes numb. Like, nearly drooling numb.

But only with sprints. My heart rate is 200-204bpm, which is normal during my HIIT workouts-but i can be doing burpees at 204 bpm and have no ill effects.

I just think its odd, so i figured id ask if anyone else experiences it.

You could have a pinched nerve in your neck that sprinting is affecting. I can't think of anything else that would cause this other than just the pure excitement of flying.
