When headache and dizziness occur during coughing, it is likely that there is already a vascular lesion in the brain, and coughing can easily induce hypoxia, and the sense of shock to the body is also strong, which can easily induce constriction or spasm of the cerebral blood vessels, and then a relative lack of blood supply to the brain can occur, resulting in headache and dizziness. First of all, an MRI of the head should be done to rule out headaches and dizziness caused by cerebrovascular pathology. If vascular lesions in the brain do exist, an inpatient visit to a neurologist is needed for consultation, the results are often better and long-term medication is required for treatment. If there is no vascular lesion in the head, it is often the cough that causes hypoxia, and the head is less tolerant to hypoxia, so cough and phlegm treatment is more effective at this time, and cough and phlegm medications can effectively relieve the headache and dizziness caused by simple coughing.
