Causes of joint noise: Generally, joint snap can be divided into physiological and pathological, and most joint snap is physiological. It does not cause discomfort to other parts of the body and does no harm to the body while making noise, so it does not need special treatment or anxiety. But some people will feel pain, swelling and other discomfort when their joints bounce. If the joint makes abnormal noise, it means there is something wrong with the joint. The common diseases in clinic include meniscus injury and knee joint diseases. This pathological fracture is common in knee, ankle, hip and shoulder. Judging whether joint ringing is a hidden health problem has a lot to do with people's living conditions. Generally speaking, the joints of young people who live at leisure are mainly caused by physiological reasons, unless there is trauma; However, once there is a person with high work pressure and frequent fatigue, more attention should be paid to the loss of local articular cartilage. Especially for sedentary people, there is less lubricating fluid between joints, which increases the loss of joint friction and makes it easier to hear this noise. For example, if meniscus injury is not treated in time, it will aggravate cartilage wear, while excessive wear may lead to degenerative arthritis and increase the burden on the body. Teachers, editors, white-collar workers and other people who work at their desks all the year round often have "ringing" joints, and the appearance of this noise just reminds people to protect our joints.
