Also, to bump an old thread, which gave me hope recently. This is about the Buffalo clinic. One poster says that the doctor there said that 90% of the patients he sees have neck injuries, not post concussion syndrome. Two posters in this thread indicate that with exercise, their symptoms improved in a matter of weeks.

Worth putting this at the top again.
