Ouch. That sounds as if it was a terrible knock.

Check out the Traumatic Brain Injury & Post Concussion Syndrome Forum

Honestly I'd post there too. There are heaps of info posts in the Sticky threads at the top of the forums too. There may even be some posts that are helpful regarding hormonal changes after TBI. The eyesight problem is familiar to me as well (had PCS myself although pretty well recovered apart from residual vertigo and some other issues).

see you there.

Regarding the MS panel. I think that does happen, yes.
You could ask over there as well. They're a lovely group and would be very welcoming I'm sure.
