Eddy,

You first need to go see a medical doctor to ensure you didn't cause any damage that might require emergency medical attention. Not that you should worry but it is better to be safe then sorry.

I would then begin researching possible neurotherapies for your brain. These include (but are not limited to) neurofeedback, vitamin/mineral balance, hormone, HBOT, diet, etc... Since you have had two head jostles in a short period of time, you may need to do some therapy to heal your brain. Good luck.
