For the past days i have interval headache and feeling nauseated to the point of vomiting. i cant figure out what's wrong?

See the Doctor: Head aches are difficult to treat, but through a good history and physical exam, a doctor should be able to figure out what may be causing your headaches and associated nausea with vomiting. Headaches/migraines can range from things you may be eating, hormonal changes, underlying illnesses, to more serious issues, etc. See the Dr. Best wishes.
