When a patient has a headache and swollen face, there are common causes. First of all, the patient may have a headache and swollen face due to staying up late every day, which can cause the brain nerves to not get enough rest and the patient drinks too much water before going to bed. It is also seen in menstruating women, who have swollen faces and migraine headaches during menstruation. Patients with pulpitis may experience trigeminal neuralgia, facial swelling, and headaches when pulpitis strikes. It is likely that the patient’s kidneys are failing and the body is not able to metabolize the toxins completely, so the urine volume is reduced and the headache and swelling occur.
