If the symptoms are not relieved, acupuncture can be used to treat the shoulder, such as the acupuncture point of the shoulder, the acupuncture point of the shoulder well, and the acupuncture point of the giant bone, in order to relieve the pain. If the pain is not relieved after treatment, it is best to go to a regular hospital for a local examination of the shoulder joint and, if necessary, an MRI of the cervical spine to rule out the symptoms of shoulder pain caused by cervical spondylosis or cervical disc herniation.
