Neck cramps are often related to the incorrect posture of the patient. Patients always lower their heads leading to stiffness and tightness in the neck and shoulders, which, after a long time, causes secondary degeneration of the cervical spine, small joint hyperplasia, disc protrusion, different degrees of degeneration of the posterior spinal ligament and supraspinous ligament, causing compression of the peripheral nerves and edema of the tissues. Therefore, when the posture is poor, the humidity of the air increases and the temperature drops, the tension and spasm of the musculofascial muscles will easily lead to convulsion. For such patients, you can strengthen the functional exercise of the neck, pay attention to keeping warm in the cold and humid environment, and pay attention to adjusting your posture especially when you sleep at night. Do cervical exercises frequently, and when the pain is severe, you can help relieve the symptoms with baking lamps, microwaves, and medium- and low-frequency electrical physiotherapy.
