Hi Habu,

I'm not Selenius, and I hope that you'll be hearing from Selenius soon, but I just wanted to say Welcome.

I'm not knowledgeable about TBI and I hang out mostly on the MS forum but I've had a few head wounds over the years and am aware of how severe they can be.

It might be a good idea to ask some questions about that abnormal sweat test, it seems to me--but that's just a thought.
