The time course can help to distinguish between different causes of ear pain. For example, if the pain started suddenly and lasted only a few seconds it could be related to barotrauma (for example when flying). If the pain is constant and has been present for a few days it may indicate otitis media or an infection. If there has been gradual increase in intensity of pain over days or weeks then this may suggest a more chronic condition such as exostosis.
