For over 20 years prior to using the DRX 9000 my lower back became an increasing problem. When I contacted Dr. Davis, it had gotten to the point that I was unable to walk across the street without experiencing significant pain. After 20 half-hour DRX 9000 treatments, I can walk as far as necessary- literally, a mile or more- without any discomfort. This year, for example, I will be able to attend and enjoy the Clark County Fair. Additionally, I have a much more positive attitude in my relationships with my family, friends and associates than I did prior to the DRX 9000 treatments.
