When a patient has a headache and is uncomfortable, the patient’s blood pressure and blood sugar are measured and the patient’s body temperature is taken. Blood tests and a CT scan of the head will be done. The main purpose is to see if the headache is caused by high or low blood pressure. Some patients may have headache due to hypoglycemia, and some patients may have headache due to vascular disease in the head, such as a small amount of cerebral hemorrhage. If the patient is experiencing hypothermia, consider that the patient may have a bacterial infection or viral infection in the body, which causes the patient to have a symptomatic headache. After ruling out these causes, consider that the patient may be experiencing an attack of migraine symptoms. Migraines can be triggered by many factors, such as eating spicy and irritating foods, excessive mental stress, and little sleep.
