RSD PUZZLE #3
RSD and TMJ Pain

"Your injury was to the right hand causing RSD. This is in no way related to the right TMJ pain or the loss of teeth that you have developed since".

As remote and unrelated as they may seem, RSD can and does result in cranio-cervical pain, muscle spasm, TMJ disease and deterioration of the teeth.

It is quite common for patients who have suffered from foot or hand injury to develop low back pain, neck pain and headache. One common manifestation of RSD in response to pain is muscle spasm, and motor dysfunction. This can be in the form of flexion deformity of the extremity, difficulty with walking, flexor withdrawal of the muscles of the extremity, and lumbar and cervical paraspinal spasm. As a result, the patient develops muscle tension headaches, as well as spread of the muscle spasm to the facial muscles with resultant stress on the temporomandibular joint (TMJ) and severe pain and spasm around the TMJ.

With passage of time, the same phenomenon results in chronic trauma to the TMJ as well as clinching of the teeth and trauma to the teeth. The patient develops severe pain in the distribution of trigeminal nerve (sensory nerve for the face) and develops moderate migrainous vascular headaches (trigeminal vascular headaches).

In later stages of RSD the immune system becomes disturbed, and the patient develops poor oral hygiene and dental deterioration.

Long-standing unilateral (one sided) spasm of cervical paraspinal muscles causes increased input of pain into the upper portion of the cervical spinal cord. As a result, a referred pain develops with resultant facial pain and secondary muscle spasm around the TMJ and the jaw. The same referred pain causes migraine headaches, TMJ pain and chronic stress on the teeth with dental deterioration.
