Headache is a very common clinical symptom caused by many reasons, which should be analyzed in conjunction with the specific form and trigger of the patient’s attack: 1. If the patient has headache, general weakness, and the desire to vomit under the sun’s exposure, this situation should be considered to be caused by heat stroke. If a patient suffers from heatstroke in a hot outdoor environment for a long time, he or she should be hydrated, go to a ventilated place, and lower the body temperature to relieve the symptoms. 2. But clinically migraine is a recurrent headache disorder, which is a functional cause. 3. If the patient has headache, generalized weakness and vomiting, it should also be considered as acute gastroenteritis, and attention should be paid to measuring the body temperature.
