The answer is that these injuries may be life-long, and years later, every week or month or so when the
pain starts, you have to get out the axial
traction device and use it for s few minutes two or three times a day. You can do this at work. The devices come with a water bag, which you discard. There is a head strap that attaches to a horizontal bar that has a center hook. A rope attaches the center hook to a cup-hool in the opper beam of a doorway, for example.
