non-concussion related: I saw a chiropractor for many years after a car accident and it was finally explained to me that I have "loose ligaments" and shouldn't see a chiropractor because those adjustments continue to loosen them. After stopping seeing the chiropractor and working with a PT, I was finally able to realize some recovery. (Argh, all those wasted years!)

Concussion-related - I am now seeing a Dr. of Physical Therapy who is also a Certified Orthopedic Manual Therapist and he has helped me a lot. After the first or second visit, the pressure inside my head, fleeting sharp headaches and transient dizziness stopped. Now we're working on the outside of my head headaches which are longer, but less painful, and the slight dizziness that comes with them.

Good luck,

Jenn
