First, frontal and bilateral temporal headaches: Patients have mainly vague pain or swelling pain. Such headaches are usually seen in muscle contraction headaches or headaches caused by high blood pressure because of poor long-term blood pressure control. Second, one side of the occipital and temporal region: the pain is mainly tugging-like or discharge-like, and the duration is very short, even a minute or even a few seconds of paroxysmal attacks, consider that there may be neuropathic headache. Third, full headache: If the patient has a full headache with distension or severe headache, it is possible that the headache is caused by intracranial infection. Fourth, bilateral occipital: If the headache appears in the occipital area, consider that the patient has cervical spondylosis or headache caused by low cranial pressure after lumbar penetration.
