What Is The Treatment For Kyphosis?

I have a kyphosis with bone spurs on the anterior surface of the vertebra and there is a moderate decrease in disc space between this area. Also, I have a cervical fusion.... I am a PT and have severe low back pain bone on bone in the low back and cannot sit for greater than an hour and half in the car without either pain down one leg or the other. At this time, I am in PT but my thoracic pain has not changed... Any thoughts?
