My bones pop sometimes
Some people pop more than others. The knuckles, knees, ankles, back and neck are fluid-filled. When you move, the joint stretches and gas is released creating a sound. A noise that’s more of a snap than a crack may be a tendon that’s moved out of place and is returning to its position. Is it painful? Then see a doc, says Dr. Edward G. McFarland, director, Adult Orthopaedics Division, Johns Hopkins University School of Medicine, Baltimore. No pain, no worry.
