Well, from my experience none of them know for sure; they work off of guesses, and see if the treatment works. Then if not, they adjust their guesses, and the treatment, and go from there.

I saw my new neuro today, and although he was more interested in helping me than the Work Comp neuro, he wasn't even willing to call what I had a concussion b/c I was not unconscious, or at least confused for a while. He decided I have post traumatic headache with some possible nerve damage. But he's guessing, just like they all do, and proscribing me some medication that is supposed to help both headaches and nerve pain. If that doesn't work, I guess he'll try something else.

I would try not to worry about all of this; it's par for the course it seems. Plus you all in Canada have a single payer system so the testing and treatments are even more rationed than down here, so they are not going to run expensive tests if they can guess a correct solution. The good news is, even if your symptoms overlap a great deal, so do the medications and treatments; so, it's likely as not he/she will guess correctly and you will have relief.

But also do your homework and be your own advocate. I don't know if nerve damage would have come up today if we had not brought it up a few times to this neuro. I know most doctors hate patients that do research, but in the area of concussion and brain injury in general, from what I've seen, it's absolutely critical b/c there is so much misinformation out there.

Good luck, hope you get some relief soon!
