Wow, I am sorry you had such a horrible experience with your doctor. That is awful.
I will have to say, though, that if I had just talked to my primary care provider, that is about the level of care I would have gotten too. She knew nothing about brain injuries whatsoever. Most of what I found out or got as treatment were things I learned about through this forum and other research I did. It is truly disgraceful how ill-informed the medical community is about concussions.
Here is a detailed document from the Ontario Neurotrauma Foundation:

I don't know if you could ask your doctor to read this and say that you would like to discuss it at your next appointment? I had some success with this strategy when I found information I thought my doctor should know but didn't.
Hope you find a way to get some treatment. In the meantime, stay strong.
