The pain in half of the head should be analyzed in the context of the patient’s past history of headache, the trigger of the headache attack, and the nature of the pain. If the headache occurs after a cold, it may be caused by occipital neuralgia or temporal neuralgia. Occipital neuralgia is usually in the posterior occipital region, while temporal neuralgia is usually near the temples, and may be caused by a cold or flu. If the patient has a history of migraine and has pain in half of the head, it may be caused by migraine attacks after staying up late, sleeping poorly, or stimulated by excessive stress or exertion, and may be accompanied by aura symptoms, such as bending of light or flashing lights when looking at things before the headache attack. For migraines, zolmitriptan tablets can be taken orally as indicated to terminate the headache attack.
