There are two possible reasons for this symptom: one reason is that the shoulder and neck, which normally have poor blood circulation, once after shoulder and neck massage, the local blood circulation suddenly increases, resulting in changes in the body’s blood pressure, thus producing the symptoms of dizziness. There may also be a slight lack of cerebral blood supply, but the possibility is relatively small. Another reason, the possibility is relatively large, is due to their own cervical spine disease, resulting in shoulder and neck discomfort symptoms, after the inappropriate, relatively incorrect shoulder and neck massage, stimulating the internal carotid artery, resulting in changes in blood supply to the head, resulting in dizziness symptoms, there may also be headaches, nausea, vomiting and other symptoms of discomfort. Therefore, once this symptom occurs, you should try to stop shoulder and neck massage, and go to a regular hospital to check the local CT to exclude related diseases, and then carry out targeted treatment.
