A rattling sound in the neck may be caused by the following two mechanisms: First, it may be due to the patient keeping the neck fixed in a certain posture for a long time, and then when it suddenly moves afterwards, this kind of abnormal sound will occur due to some small joints of the cervical spine being misaligned for a short time, or there being a change in pressure. Although this situation is physiological, that is, there is no pain symptoms after the ringing, but over time it will lead to cervical spondylosis in the neck. Second, it may be caused by pathological conditions, such as cervical cervical spondylosis or subluxation of small joints, after which the patient will have a clicking sound when moving the neck, and there will be obvious neck pain, stiffness and unfavorable movement after the ringing. Some patients have the habit of moving their cervical spine excessively hard when they have neck discomfort, and then feel some relief after the clicking sound occurs, but this is very incorrect. Because there may be underlying diseases in the cervical spine, such as cervical spondylosis, excessive movement at this time may provide temporary relief, but may also lead to aggravation of the disease, such as more serious dislocation of small joints, or damage to certain ligaments and bones.
