Dr O'Connor is the best ! 20 yrs of chronic back pain is gone for 2 years now. My orthopedic surgeon sent me to Dr. O'Connor 2 years ago and said to try it and if it didn't work we would do surgery. After only 3 weeks of care the pain was gone. I have only had to see him one or two times over the last 2 years. Turns out my Orthopedic surgeon and my primary care Dr both see Dr. O'Connor for their back pain. You would be nuts not to see Dr. O'Connor if you had a problem.
