The more common cause of muscle stiffness in the neck and shoulders is cervical spondylosis, because cervical spondylosis stimulates the nerve roots and causes muscle stiffness, sometimes accompanied by pain. Treatment can be physiotherapy, such as localized hot compresses, with creams, such as flurbiprofen babu cream. If the stiffness of the neck and shoulder muscles is obvious, you can choose tizanidine and other drugs for antispasmodic treatment. At the same time, pay attention to personal habits and try to avoid long-term fixed neck inactivity, such as prolonged use of computers, playing with cell phones, working at a desk or reading newspapers, etc. If the symptoms do not improve significantly after treatment, it is still necessary to improve the magnetic resonance examination of the cervical spine in time, so that the degree of cervical spondylosis and the specific segment can be more accurately determined.
