Any time I took time off, it just came back with a vengeance as soon as I started training again. I finally did chins, curls, and the theraband flexbar exercise and just continued training. Hurt like hell. Guess what? It slowly got better and finally disappeared. And I didn't miss any training.
At it's height, my golfer's elbow was so bad I couldn't press the palms of my hands together to wash them.
