For people who suffer from both migraines and temporomandibular joint disorder (TMD), the two conditions can seem so bad they’re related. Now, a new study by the National Institute of Health (NIH) has discovered they might be.

An estimated 12 percent of Americans suffer from debilitating migraine headaches - headaches that in addition to causing agonizing pain can cause everything from nausea to light sensitivity and dizziness. But while for some of those migraine sufferers, the pain stops there, the NIH has revealed that those who suffer from migraines are three times more likely to suffer from another debilitating condition: TMD.
