- Pain in muscles of mastication, the TMJ, or the periauricular area, usually worsened by manipulation or function
- Asymmetric mandibular movement with or without clicking
- Limitation of mandibular movements
- Pain present for minimum of 3 months
- Consider imaging if history of trauma/facial trauma
