TMJ headaches are one of the more common TMJ symptoms. These headaches can often be so severe that they are mistaken for migraines! Whatâs worse is that the pain of a TMJ headache can actually trigger a really migraine, only adding to the pain!

Unfortunately, these headaches can last for extremely long periods of time.
