My ears became very sensitive to noise. air pressure in a moving car with windows down bothers my ears and i can't stand it. what's wrong with me?

Pressure on ear drum: This can happen for a few different reasons. The problem could be originating in your brain, such as in people who experience this as part of a migraine headache syndrome. More likely, it is a problem with pressure in the inner ear which can occur with allergies, or eustachian tube dysfunction. It can also happen when changing elevations quickly, like driving up or down a mountain.
