After suffering a traumatic brain injury in a car accident, I went to a neurologist, physical therapy, speech therapy, a sports injury doctor, and a general practitioner. None of them were able to provide relief, and a couple of them made things significantly worse. I had given up hope of recovery when a friend referred me to Dr. Spencer Zimmerman. Within two weeks of treatment, my dizziness was gone, my nausea was much improved, and I finally had a sense that I could at last heal from what had completely derailed my life.
