There are the following reasons why your neck hurts when you turn it: 1. It may be due to muscle strain in the neck, or pain caused by muscle spasm in the neck. For example, prolonged repetition of a certain posture, sleeping on a pillow, prolonged looking down at the cell phone or computer can lead to chronic strain on the soft tissues of the neck muscles, resulting in the symptoms of pain when the neck is turned. 2, consider the small joint dysfunction of the cervical spine, because when the neck is turned, there may be embedded synovial membrane around the neck and friction of the articular cartilage, resulting in painful symptoms. Therefore, if your neck hurts when you turn it, you can avoid strenuous activities, rest in bed, wear a brace to fix it if necessary, and give local topical creams for pain relief and symptomatic treatment. If there is no relief within a short period of time, you must go to a regular hospital in a timely manner to improve the cervical spine MRI and choose a more reasonable treatment method after clarifying the cause, so as to relieve the symptoms of pain when the neck is turned in a timely manner.
