Temporomandibular Joint (TMJ) Syndrome (cont.)

Pain in the facial muscles and jaw joints may radiate to the neck or shoulders. Joints may be overstretched. You may experience muscle spasms from TMJ syndrome. You may feel pain every time you talk, chew, or yawn. Pain usually appears in the joint itself, in front of the ear, but it may move elsewhere in the skull, face, or jaw.
TMJ syndrome may cause ear pain, ringing in the ears (tinnitus), and hearing loss. Sometimes people mistake TMJ pain for an ear problem, such as an ear infection, when the ear is not the problem at all.
When the joints move, you may hear sounds, such as clicking, grating, and/or popping. Others may also be able to hear the sounds. Clicking and popping are common. This means the disc may be in an abnormal position. Sometimes no treatment is needed if the sounds give you no pain.
Your face and mouth may swell on the affected side.
The jaw may lock wide open (then it is dislocated), or it may not open fully at all. Also, upon opening, the lower jaw may deviate to one side. You may find yourself favoring one painful side or the other by opening your jaw awkwardly. These changes could be sudden. Your teeth may not fit properly together, and your bite may feel odd.
You may have trouble swallowing because of the muscle spasms.
Headache and dizziness may be caused by TMJ syndrome. You may feel nauseous or vomit.
