There is an old line about the guy who goes to the doctor and says, When I do this, it hurts. The doctor replies, Then stop doing that.

You are a better critic than outsiders. If it makes you feel bad, don't do it.

I would be even more concerned with the double whammy effect of the high sound volume and physical motion. The sound creates an electro-chemical (processing the sound) and physical stress (high amplitude, all frequency vibration). The physical motion causes a physical (high amplitude very low frequency vibration) and chemical ( blood flow abnormalities, high blood pressure, high adrenaline levels ) stress. Add them all together and your brain is being stressed in every way possible.

I would not be surprised if there is a cumulative effect that adds to your previous injury residuals.

From my experience, I know to stay away from such events, even when I think I can tolerate them.
