I came in from a motor vehicle accident and couldn't turn my neck at all. I have had headaches at the base of my neck for 10 years and had to carry a bottle of Tylenol everywhere I went. I also had numbness in my fingers after the accident. I now have no more stiffness in my neck, I have complete feeling in my fingers and my headaches have subsided. My kids used to have to help me when driving because I couldn't turn my head, but now I can drive without assistance or needing anyone in the car with me.
