Before I received any treatments, I suffered a lot with frequent headaches. The massive headache would move on to my eyes and then later I would even feel nauseous. I would always have Advil or Tylenol with me because I had such frequent headaches. After receiving treatment my headaches disappeared for good and it was hard for me to believe that it was the power of the adjustment. Even pain killers wouldn’t get rid of my headaches but through Dr. Parks’s adjustment my headache is gone for good. Thank you so much Dr. Park~~~^^
