Thankyou Dr. Corenman for reponding to my question. I followed up on your reply by reading more about conditions on your excellent website. I failed to mention that during my last examination based upon an xray the surgeon said one of my vertebra where the disc is gone is displaced 8 mm. I did see a chiropracter on several occasions during the last two years, but it did not help and I have myself convinced the manipulation did more harm than good. Maybe I need to try again. What qualifications or skills should I be looking for in a chiropracter to help with my condition?
