I have a headache for 4 days now, pain is mild but i still can't get out of it, what can i do to stop it?

Get evaluated: Headaches can be a concerning symptom and can have many causes. Some are deserving of emergent treatment. Warning signs are chronic headaches that suddenly change in quality or intensity, multiple headaches a week, new onset headaches that affect one's ability to function, associated vomiting, associated dizziness/double vision/neck ache/fever/weakness, or the need to take daily pain medication.
