Neck and shoulder pain may be related to physiological factors such as poor posture or cold, or it may be caused by pathological factors such as neck and shoulder fasciitis, cervical spondylosis, frozen shoulder, trauma, etc., which requires timely consultation to find out the cause of the disease. 1. Physiological factors: prolonged bowing of the head, incorrect sleeping posture or working in a cold environment will lead to spasm of the neck and shoulder muscles, thus causing soreness and pain, which can be improved and relieved by improving the sitting posture, paying attention to rest and keeping warm. 2. Neck and shoulder fasciitis: Because of the richness of neck and shoulder muscles and fascia, repeated pulling and stimulation will cause local inflammatory reaction, thus causing pain and discomfort, especially after cold and exertion, which is often aggravated. 3. Cervical spondylosis: due to cervical spine degeneration and disc herniation, it will stimulate the muscles of the neck and shoulder or compress the nerves, thus causing pain in the neck and shoulder, partly accompanied by numbness and weakness of the upper limbs. 4. Frozen shoulder: Due to the adhesion of the soft tissues in the shoulder joint, aseptic inflammation occurs locally, which will also cause neck and shoulder pain, and is often accompanied by limited shoulder activities. 5. Trauma: when too strenuous exercise pulls the muscles, causing neck and shoulder muscle injury, lactic acid-like substances accumulate too much, can also trigger soreness. Neck and shoulder pain, through rest and warmth and other self-conditioning can not be improved, you should consult a doctor in time, standardized treatment, to avoid delaying the condition.
