There are many causes of neck stiffness, such as poor posture in life, e.g. improper sleeping posture, prolonged looking down at the mobile phone or work, prolonged standing or improper sitting posture, etc. If you live in a humid and cold environment for a long time, it can also cause muscle cramps and result in a stiff neck; in addition, diseases such as cervical spondylosis, osteophytes and tumours can also cause pathological neck stiffness. Therefore, when physiological neck stiffness occurs, traction, massage and physiotherapy can be used for treatment; if it is pathological neck stiffness, you should go to the hospital in time to have a physical examination, CT examination, etc. to identify the cause and follow medical advice for symptomatic treatment.
