I also had a problem with Golfer's Elbow in my right elbow...probably came from lifting my 120 lb son into and out of his bed and wheelchair...used an arm brace on and off for about two years and did a lot of inverted elbow stretches. What eventually cured it was the rest that came after rotator cuff surgery on my right shoulder...although I wouldn't recommend this particular cure for anyone.
Rest and not using it to lift for several months was the real cure...we were fortunate to find help with our son while I was not able to lift him.
