Same here with lower back pain from football injury in college. When I have a flareup of arthritic pain, I slap the Actipatch on at night and in the morning I am fine. That was NOT the case prior to using Actipatch. Previously, if I aggravated my back from some activity during the day, the next morning waking up was painful. For me it is a life saver. That is why I always hoped that this would be noticed and discovered in the massive market of sports participants, professional and amateur.
