"stuffed" ears.
 

Everytime I ride, my right ear "closes" as if I have just climbed a mountain (and I can tell you I haven't - at most 700 ft of climb probably) or got water in my ear. Naturally, the colder it is the more likely it will happen. If it's cold enough to wear a hat, I'll make sure my ears are covered, and that helps some, but it still happens even if it 80 degrees. Does anyone else have this happen? Have you done anything to improve on it? Also, my ear will stay "closed" for probably an hour after the ride. This also has happened when I've gone ice skating, so obviously there is something relating to the air circulating past my ear.

Never used to happen particularly in the cold, but could occur at any time and not only on the bike. I had an ear infection for about 2 years before I went to the quack's. 2 weeks on anti-biotics cured it.

mee toooo. i find it really anoying cuz i hear myself when i talk. sometimes bending my head/body towards my stomach and trying to blow air out of my nose while pinching my nose helps.

sounds like you have eustachian tube dysfunction
