In my opinion what you have on hand might actually cause you to further injure yourself. The biggest problems I've had over the years with joints is that my muscles overpower my genetics. While it may help in the short run some, you may become overconfident in what you will actually be capable of.

You are either going to have to suck it up or have the surgery. Trust me, I feel your pain. I tore my elbow up this winter and have yet to see the doc because it might put me out of work for a few months. Just trying to hold on until the winter comes.
