Fire may cause headache because when a person’s resistance decreases, the symptoms of fire may appear, such as tiredness, lack of sleep, emotional depression, all of which may cause symptoms of fire, which may trigger migraine attacks in patients with previous migraine. If you have no previous history of headache, you should be alerted to the sudden onset of a new headache, especially if it is more severe. A cranial CT should be performed to rule out brain hemorrhage or subarachnoid hemorrhage. If there is no such condition, you can take pain medication to relieve the headache, increase the body’s resistance, and exercise actively, which may reduce the headache attacks.
