I have had a sore head for 4 days its starts in the morning when i get up with a pain at the side then works around my head as the days go on just wondering what could it be?

Head discomfort: This may be a muscle contraction type headache which is almost always stress related. This is usually more of a steady dull ache rather than a throbbing migraine type which often has accompanying nausea. If you don't get relief with Tylenol (acetaminophen) or Advil type medication, a neurologist is best qualified to diagnose and treat your headache.
