My inner ear hurts whenever I'm driving, like I'm under water, why?

Hello, I'd definitely recommend seeing your family physician regarding any personal inner ear pain. No vehicle can cause this; perhaps driving conditions could exacerbate a health problem, but a vehicle running condition is not at fault. I can't really recommend anything -- except a personal evaluation at a physician, and perhaps a vehicle evaluation at a shop near you.
