Straightening of cervical curvature is usually caused by acute neck muscle sprains, myofibrillitis of the neck and shoulder, or root-type cervical spondylosis. Depending on the cause, different methods of treatment are used. Commonly used treatment methods include: general treatment, physical therapy and other methods. 1. Acute cervical muscle sprain: due to muscle pain and spasm, the muscle pulls the bone, resulting in straightening of the cervical curvature. At this time, you should reduce the neck muscle activities, hot compresses on the sprained parts to accelerate muscle recovery. 2. Cervical and Shoulder Muscle Fibrosis: Due to long-term poor sitting posture and other reasons, it causes cervical and shoulder muscle fibrosis, which leads to muscle spasm and straightening of the cervical curvature. You can put a towel roll in the cervical vertebrae to keep the normal curvature of the cervical vertebrae when doing jaw recovery action, keep tightening for 15~20 seconds, 4~6 groups per day. 3. Root-type cervical spondylosis: inflammation of the joints of the neck, joint periosteum and joint capsule swelling, stimulation of the peripheral nerves, causing tension in the neck and shoulder activities, resulting in straightening of the curvature of the cervical spine. In the face of this situation, you can massage the inflamed joints to relieve muscle tension and weaken the pressure on the nerves. In addition, there are other causes of cervical curvature straightening, such as muscle tension weakening, neck tumors, etc. If the curvature has not recovered significantly over a long period of time, it is recommended that the patient go to the hospital in a timely manner, and comply with the doctor’s instructions for standardized treatment.
