Not trying to be a know-it-all here, but just in case this is correct and NOT common knowledge. I had it in my right elbow for about 6 months several years ago, and happened to mention it to my sister-in-law who was a practicing nurse practitioner at the time. She said the medical fix was to open it up and basically scrape the hell out of the affected tendon, as apparently tennis elbow is not enough damage on its own for your body to send help to the hurt area. Increase the hurt and the body heals it up. Yeah, I did not go that route, but about 4 months later I was asked to play in a charity golf tournament (no, I suck at golf, hadn't played since college). Par 3 hole and I buried the 7 iron about 5 inches behind the ball, torqued the hell out of my elbow and made the rest of the day and following week pretty miserable, but within 2 weeks the tennis elbow was gone, and has not returned. Cannot say that was the fix, but I definitely increased the injury and it ultimately went away...I didn't ask any questions...
