Oh yeah, I know this one. I have a terrible time with my ears.

They tingle, and, feel, at times, like a knife is being stabbed into them. I have screamed out in the supermarket.

The worst part is that I experience periods of deafness. It happens everyday. It usually only lasts for several seconds or a few minutes, but once I couldn't hear out of my right ear for four days. I wondered if my hearing would ever come back.

All my neuro said was, "your auditory nerves are damaged." No kidding, Dr. Obvious. He didn't offer any help.

Like you, I smacked the side of my head. Funnily, while the left side of my head hit the driver's side window, I have more trouble with my right ear.
