Bones that ring when you move may be caused by several reasons. First, there may be a bone related injury. For example, there is a fracture inside the bone or a dislocation inside the joint around the bone. In this case, the bone in the activity has a very obvious sound, and will be accompanied by very severe pain and local swelling, deformity, bone rubbing sound, bone rubbing feeling and a series of other manifestations. Secondly, it may be caused by the tendon lesion around the bone, for example, the tendon is inflamed due to long-term overuse, cold and other factors, and the swollen tendon may pass through the narrow tendon sheath and produce the corresponding sound. Because the tendon is attached closer to the bone, the tendon’s ringing may cause the patient to mistake it for bone ringing. Thirdly, it may be caused by joint lesions around the bone, such as osteoarthritis or damage to the meniscus, cartilage, or ligaments inside the joint. In this case, there will be a strange sound in the joint during the activity, and the patient may mistake it for a bone ringing.
