I had a very bad concussion after falling from a trampoline and was sick for about 3 days after the accident, throwing up, unable to stand for little periods of time, and unable to eat much food. I visited an MD, got examined and had no major brain injuries, but I still was feeeling terrible after the accident. I then went to Dr. Eileen at Crossroads, and was astonished at how fast I healed. Within two adjustments to my neck I was starting to regain memory, getting much less dizzy, and finally not having the terrible headaches. HIGHLY RECOMENDED
