Central Sensitization Is Another Explanation
People with TMJ are 5.5 times more likely to report pain in other parts of the body than those without the condition. People with TMJ are also more likely to develop several other pain conditions, commonly called chronic overlapping pain conditions. These pain conditions commonly occur with each other, too. For example, people with migraines are also more likely to have lower back pain.
One explanation for the frequency of multiple pain sites is central sensitization. This theory states that if the body experiences enough chronic pain, it begins to anticipate pain. It then begins to interpret even non-pain signals as if they were pain. The theory is supported by some evidence, though not enough to make it conclusive.
Some versions of the central sensitization theory give TMJ a central role in the development of chronic pain. This might be related to the fact that pain from the jaw comes along the trigeminal nerve, the largest cranial nerve. Getting TMJ treatment in Detroit might help head off the development of other pain disorders.
