I had a bad case of 'tennis elbow' from over use at work(not playing tennis,...I work in a health food store receiving and shelving hundreds of bottles of supplements each day) nothing, including physical therapy, did much to relieve the pain. After only a few days of doing the exercises suggested with the Theraband, I have had dramatic improvement. Absolutely wonderful results!
