For discomfort on the left side of the neck, the patient should be asked whether there is any neck trauma or long-term low back bending. If there is pressure pain in the muscles on the left side of the neck and pressure pain in the spinous process and paravertebral area of the cervical spine during physical examination, the patient can be seen by a spine surgeon. If the discomfort on the left side of the neck caused by neck muscle strain or cervical spondylosis is ruled out, it is recommended to consult the ENT department and, if necessary, perform laryngoscopy to rule out foreign bodies in the pharynx. In addition, patients with hyperthyroidism may also suffer from soreness and swelling in the neck. In addition to these symptoms, a series of clinical manifestations such as increased blood pressure and increased heart rate may be associated with hyperthyroidism.
