What symptom suggests non-musculoskeletal origin?
Correct Answer:
Paresthesias
Explanation:
Paresthesias signal nerve involvement rather than a problem with muscles or the joint itself. In TMD, muscle-related issues show up as pain with chewing, muscle fatigue, or tenderness, and joint involvement often presents with sounds like clicking or crepitus. Ear fullness can be related to TMJ or middle-ear effects but doesn’t inherently point to neural issues. When a patient reports abnormal sensory changes such as tingling or numbness in the jaw or face, it suggests a non-musculoskeletal or neuropathic origin, warranting broader neurologic or nerve-focused evaluation.
