Experience pain behind skull, left side above left ear. Been 3 days after night of bowling and some drinks. Feel when shake head?

Go to ER. The symptoms you are describing could mean anything from a simple viral associated headache, a pinch nerve in your neck or an atypical migraine to something more serious such as meningitis or a leaking aneurysm. In short it needs an examination by a doctor immediately to rule out anything more sinister.
Probably OK. If it is not too severe it is probably nothing to worry about. Give it a few more days If the pain is severe or still there in a few days please see a doctor.
