If you had existing pain, don't be surprised if a new frame doesn't cure it immediately. It took some time to get the injury, it will take some time for it to heal.
When I had TE, I went to an arm surgeon. He put me on cortisone injections for a period of time for relief. A racquet/string change did make a big difference, but it took time.
