I have been having headaches for 2 days now ?

Need a full story: Headache is actually a complex topic. Your past history of headaches, the description, the location, associated symptoms, relation to stress, menstrual periods, family history, etc are all important to diagnose what type of ha u have. Important: if you ever experience the worst ha ever--go to er. New or more frequent or severe ha than u have previously experienced needs work up by physician.
