I too had tennis elbow. My first doc told me to do the same, alive and ice/heat at night. But as it kept kept persisting I went and got it looked at again. Did 6 months of physical therapy but still wouldn't go away. My daily work required me to keep using it as well as detecting. Just thought i could ignore it, I couldn't. Finally had surgery in October and believe me it's not one you want. Minimum 4 months without using the arm at all. Then slowly it gets stronger. It's finally better but it was long and frustrating, had to learn to do everything with my opposite hand. Just saying don't ignore it. It can go from a strained tendon to a torn off the bone tendon and surgery is necessary. Good luck and HH
