No, I've heard of guys saying it made their tendons hurt while cycling it, I have never felt that but heard the stories. Only thing I've heard of to help sore muscles or joints is cortisone. It's supposed to be a real uncomfortable shot and was told it can make the muscles harden if used to much. Again I don't know how true the last part is so don't quote me on it.
I have a problem and have had for quite a few years with my left arm. I got a good round of tendonitise and have been to my doc, a specialist and physical therapy. None of it worked. I was getting deep tissue massages after being iced down for about a half hour, then was getting dexamethazone (SP?) treatments. They hook up this little electrical machine to some patches and put the meds on the patch and the electricity causes it to absorb into the body on the spot you need. Did that for like 6 weeks and nothing. Still hurts when here and there, mainly when doing back or bi's. I just stop doing the exercise I was doing if it starts to cat up and try something else that doesn't bother it as much.
