Get evaluation: Should include excluding causes for headache. Get a your blood pressure checked, eyes examined and consider decreasing the stress in your life by giving of yourself to an event/person that can't pay you back. Doing something you are good at for someone who can't return the favor will decrease feeling overwhelmed and help refocus your energy. Note, you should have a brain mri. Not extreme.
