Symptoms of headache after intercourse: a. Consider neurovascular headache. Neurovascular headache can be triggered by many reasons, such as excessive mental tension. During intercourse, consider that the patient may be overly excited or the head and neck muscles may be overly tense, and then the fascia of the neck may release pain-causing substances and cause headache symptoms. Second, consider whether the patient has elevated blood pressure, and suggest that the patient should have his blood pressure measured. Third, the patient may be in a state of anemia, and the patient may not be able to tolerate too much physical activity, which causes the body to be in a state of maladjustment and triggers the headache. 4. Some patients may have headache due to sweating and not replenishing fluids in time, resulting in a decrease in effective circulating blood volume and insufficient cerebral blood supply. V. Some patients may experience hypoglycemia in the process of exercise, which may also manifest as headache.
