I have persistent pain on both sides of my back, not lower back, however more where the ribs end. The muscle tissue radiates pain. Was blaming it on lifting to heavy of an object, however it wont go away. had 3 acupuncture treatments, still have the on going pain. Have used heat pad and ice. I am 71 weigh 117 lbs and 5 feet 1 inches tall. Very active, not used to pain. Nancy
