With the increase of cell phone and computer parties, cervical spondylosis is also increasing and showing younger characteristics. The cervical spine is painful and makes a popping sound when you turn. This is usually the beginning of cervical spine degeneration and strain and should not be taken lightly! But usually there are many cervical spine without pain but also occurring popping, in the end what is the reason? There are several reasons for the sound of the neck. 1, tendon ligament and bone friction: when the joint activity, tendon ligament will also slide, especially when the tendon ligament degeneration, elasticity decline or appear ligament calcification, tendon ligament in the bone surface sliding, friction, you will hear clucking (small joints). 2, gas escape: In human joints, there is a fluid called synovial fluid, which is used to lubricate the joints. This synovial fluid contains some gas and constitutes a bubble in the synovial fluid. When the joint is stretched, the gas in the synovial fluid runs away sharply and a ringing sound is formed; 3, joint degeneration to form a rough V joint surface: the joint is degenerated due to degeneration, the joint surface that was smooth becomes a rough and uneven surface, and when the joints move, they rub against each other and a ringing sound occurs. There are two types of this condition, physiological and pathological. Generally speaking, only the ringing, no abnormal appearance, no pain, no activity disorders belong to physiological ringing, it does not need special treatment, and there is no need to worry too much about it; if the ringing is accompanied by pain and discomfort or limited activity, it belongs to pathological ringing, most of them belong to small joint dislocation, and need to be clearly diagnosed by the doctor’s examination, and make the corresponding treatment.
