Failed low back surgery is actually a medical diagnosis. I've had patients with this very unfortunate problem and have been able to offer a measure of relief. The total damage cannot be undone. Watch this video for very good advice. Ask your doctor pointed questions and get other opinions. Do not be afraid of hurting the doctor's feelings! He should welcome and suggest that you get other opinions. Most importantly do everything you can to avoid surgery first! A chiropractor, especially one specializing in neurology, offers an expert opinion.
