What are some ways to relieve severe headaches and vomiting?

See a doc: Severe headache and vomiting can be associated with a variety of illnesses as simple as the flu, sometimes migraine, or may be a symptom of a more serious problem. If a headache is new and severe and is accompanied by other bodily symptoms it is not time for self-diagnosis - it is time to talk to a doctor who can examine and render accurate diagnosis and appropriate care.
