Headache vs danger: There are so many causes of benign headaches that you shouldn't worry about any dangerous causes for the same. Stress, physical and mental, lack of sleep, low blood sugaR, high BP, are just some common ones. Sinus headaches, allergies and migraine etc are also frequent causes. Take some OTC pain relief, rest, relax, catch up on good sleep,check BP and then go see your doctor as needed.
