Usually, joint noise can be divided into physiological and pathological. Most joint noise belongs to the former, such as the sound of pressing fingers. This kind of sound does little harm to the body.
However, for some people, the frequency of joint noise is particularly high. Sometimes, a slight joint movement will cause noise. This is a physiological signal to us----the secretion of our joint lubricating liquid is reduced and our joint cartilage is worn out. If it goes on for a long time, it will easily lead to arthritis.
