The neck becomes stiff, mostly due to cervical spondylosis. It is common in patients who play with their heads down for a long time on their cell phones, work on computers for a long time or work on a desk for a long time. At this time, stiffness, pain and neck discomfort can occur, and the following treatment can be carried out: 1. Physical therapy. You can use microwave physiotherapy or far-infrared physiotherapy twice a day, or apply heat to the neck muscles, which is good for relieving muscle stiffness. 2. Take oral medication. You can take oral Chinese medicine, such as cervical rejuvenation granules for treatment, which can play a role in opening up the meridians and relieving pain. 3. Take oral muscle-relieving drugs.
