Any headaches that persists for that period of time and intensity needs to be evaluated properly by a physician. Proper treatment of headaches is completely dependent on the underlying cause

See a neurologist, evaluate potential of migraine headaches, engage in preventative treatment. It will help to understand what is occurring and the best approaches to deal with it.
