pfan,

I am confused. Did the dodge ball hit to the face cause renewed symptoms?

One thing you will never recover from is your brain's lack of tolerance to be traumatized. Putting your brain at risk by being in the line of fire is not acceptable. You need to stand is a safe location or remove yourself entirely from the risky environment.

The simple fact is your brain has been injured permanently. It has recovered and is recovering as much as it can. It will never recover fully. It will never be able to tolerate an impact like it could before your most recent impact.

Each time your brain gets injured, it loses more of its tolerance for future trauma. This is undisputed FACT.
