My back used to go out 3-4 times a year. Dr. Ashton discovered that one of my legs was shorter than the other one. She prescribed a heel lift. This simple lo-tech remedy, along with a series of treatments, really helped a lot. Now the pain is much less, and I only need adjustments once a year, at most. If I were diligent about doing the back exercises she prescribed, I probably wouldn’t have to come in at all!
