If the headache is caused by migraine, or wind-cold, or wind-heat cold, it is recommended that the patient can be given a wet towel to apply hot compresses, and can also do head massage to relieve the symptoms of headache. If the headache is caused by trauma, cold compresses should be applied within 24 hours of the trauma to reduce the edema of the trauma, and if more than 24 hours have passed, hot compresses can be applied to promote the absorption of the local edema caused by the trauma. Therefore, for headache patients, most of them are used for hot compresses, and in the case of trauma, cold compresses are used within the first 24 hours of occurrence.
