Cold neck is commonly caused by the following reasons: First, cervical spondylosis: it can lead to continuous spasm and tension in the neck muscles, which will compress the blood vessels inside the muscles, resulting in insufficient local blood supply, and the skin temperature will drop, and the patient will show a cold neck, accompanied by limited cervical movement and neck pain. Through tui na, massage and cervical spine traction treatment, the symptoms can be relieved. Second, the blood circulation speed is reduced: if the patient does not exercise, the blood circulation speed of the whole body will be significantly reduced, especially the blood flow speed of the subcutaneous blood vessels in the neck, and the patient will have a local blood supply deficiency. If the ambient temperature decreases, it is easy to have the clinical symptoms of cold neck. The above clinical symptoms can be improved by increasing physical exercise and accelerating blood circulation in normal times.
