Very sorry to hear about what you've gone through. Mark has pretty much covered everything.

He's also mentioned it is OK to have one drink during a day, just not to go over that.

To respond to the question of the topic, it seems the brain is extremely delicate, and if there have been head injuries in the past, the problems build up until you're stuck with a messed-up brain, hoping it will get better.

Unfortunately, none of us know when ours or your brain problem/pain will stop. Or if it will stop. I wish doctors could help more with that.
