I read about this in your newsletters but wanted to let you bring it up in the forum.
I've suffered a few severe concussions where I was unconscious for minutes and remembered very little of the day before them. It can take a several months for the brain to recover and return to normal, or for me, my normal state of abnormal. As for the psychological impact, it isn't uncommon to have a few new fears or mental blocks afterward.
For your hand, I highly recommend a hand specialist, especially since it is still painful and not improving as quickly as it should. If ibuprofen causes problems, consider acetaminophen (Tylenol) or Naproxen (Aleve).
