What is atypical facial pain?

Atypical facial pain (AFP) is chronic pain in your face or mouth that doesn’t have a clear cause. It’s also called persistent idiopathic facial pain (PIFP). AFP can affect any area of your face, but it often causes jaw, ear or cheek pain. The condition can be difficult to diagnose and can be frustrating if you’re experiencing pain.
