May be a migraine. Do you have light sensitivity? Do you have a throbbing or pulsating headache? If yes, then you probably have a migraine. It may help you to have treatment with a medicine such as sumatriptan, or ketorolac, to have relief. Do not fear, this kind of headache does get better soon! If you do not have these symptoms, or if you do, an evaluation is also a good idea.
