Bone ringing may exist in the following situations: 1. The most common ringing is in the joint position of the human body, such as the hip joint, knee joint, shoulder joint, spinal joint and so on. Rattling in the hip joint is usually caused by misalignment of the hip joint, which is directly related to the state of the ligaments around the hip joint. Some middle-aged and elderly people do not exercise regularly, and the endurance strength of the muscles and ligaments is not enough, so when walking or doing other movements, the hip joint will pop due to ligament relaxation. 2. The popping sound in the knee joint is usually caused by the damage to the meniscus of the knee joint or the free body in the joint, and when moving the knee joint, the popping sound will occur due to the squeezing of the damaged meniscus or free body cartilage. 3, Patients with muscle injuries may also experience popping due to sudden movement, and people with congenital rib cartilage discontinuity may also experience bone rattling when sneezing, coughing, or breathing deeply.
