I have neck surgery in 2010 because of an accident, after the surgery, I was unable to walk for a year. Thanks, to some physical therapy I m walking, but about 3 years ago I suffers from severe pain from irradiate from my left leg passing trough my spine my back and my neck. The pain is so severe sometimes if I don t have medicine I passed out. I went to a lot of physician, but everything stay the same. DO YOU HAVE AN ANSWER FOR ME?
