I had chronic low back pain every day for seven years. I felt like my spine was a 2″x4″ board every morning. During the seven years, I had PT with two other offices with minimal to no gains. After the first session with Chris Dukarski which included a manipulation and some exercises, the pain and stiffness were gone. No joke. I felt my back and core responding in subsequent visits and after completing five weeks of office and home sessions my back is pain free and feels ten years younger.
