There are many clinical conditions that can cause throbbing pain on one side of the neck. First, the pain caused by the muscles on both sides of the neck. The muscles on both sides of the neck are mainly the sternocleidomastoid muscles, which cause pain due to muscle ischemia and hypoxia when the patient holds his head up for a long time or when the neck gets cold. Patients can feel obvious pressure points on the left side of the neck, and there will be clinical manifestations of stiffness and soreness. Hot towels can be used for hot compresses, and physical therapy, such as acupuncture, can also be done in the hospital when conditions permit. Finally, in addition to the muscles on both sides of the neck that can cause pain, abnormalities in the thyroid gland and lymph nodes cannot be ruled out. If there is no obvious pressure point and the effect of hot compresses and rubbing is not good, you can choose to go to the hospital for further consultation to rule out abnormalities in the thyroid gland and lymph nodes through neck ultrasound.
