I too had PMR a few years back. I am completely pain free now. They put me on prednisone and while it definitely was a miracle drug at the time, it led to other issues and I ended up on 5 different medications as a result. I slowly weaned off all drugs and I am completely fine today. I used to be a long distance runner and never did return to that; however, I am completely pain free to answer your question. There are other ailments that can cause pain, so perhaps there is a bit of arthritis or carpel tunnel if you are still experiencing pain. The blood tests should reveal if the pain is related to the PMR or if it could be something else.
Good luck - it is an awful disease for sure.
