Ernest Syndrome arises when the stylomandibular ligament, which attaches to the jaw, becomes inflamed and produces feelings of pain in several areas of the head and neck.

This ligament grows from a bone under the ear floor and attaches to the back of the lower jaw, just about one-half inch beneath the ear lobe.

It limits jaw movement, keeping it from opening too wide or moving forward too much.
