Hello
I had tennis elbow 4 years ago that was severely painful at all times
I went to a doctor who is achronic pain specialist and he told me that he felt that it was caused by worry and tension. He offerred to give me a cortisone shot as he said they sometimes helped by loosening up the nerve. (Cannot remember exactly what he said.)
Well the same day it started to get better. He told me that it was because I was doing something for myself by going to see a doctor. I still have it vaguely but only notice it when I think about it specifically
Anyway it sounds like you are on the right track.
Best of luck
Helen
