See your doctor: You should be evaluated. There are many possible causes, some of which include high blood pressure, low blood sugar, dehydration, obstructive sleep apnea and brain tumors.

Headaches: Your headaches could be coming from tension, dehydration, lack of sleep/poor sleep, skipping meals, stress, sleep apnea/snoring/teeth grinding, or chronic sinus problems.
