My Uncle who was a line man, injured his back from falling off a pole while working, in the '60's, and back then the answer to the pain was cortisone shots, he got the shots once every three months, for years. Now, he can break bones in his feet just by walking across the floor. The Dr's now know that it is a dangerous treatment when continues for a long time. I wouldn't trust that drug. I have had one shot of cortisone in my foot for bone spurs and plantars faciitis, it did not help me at all. And it was very, very painful, even if it had worked I don't think I would have the shot again, I can usually handle pain, but this was intense.
