We report the case of a 44-year-old woman with chronic facial pain. She was treated with several analgesics, prophylactic medications and infiltrations, but all treatment modalities were ineffective. Finally, the diagnosis of medication-overuse headache complicating migraine without aura was made and an appropriate treatment was initiated. Migraine is a very common primary headache and rarely presents as isolated facial pain. Stimulation of the dura with activation of the trigeminovascular system can result in pain in any of the three divisions of the trigeminal nerve. This is the anatomic basis of migraine pain presenting as referred pain to the second division of the trigeminal nerve. The atypical presentation of migraine pain can easily lead to inappropriate treatment regimens.

This patient had chronic facial pain and was treated with numerous drugs and then diagnosed as medication overuse headache and complicating migraine without aura. They used drug therapy but no mention is made of use of an orthotic. This myoptic type of treatment is common. Throw a drug at the problem , then another and another.

The conclusion that atypical pain can lead to inappropriate treatments regimens speaks for itself. When pain is from the maxillary branch of the trigeminal nerve it would seem appropriate to evaluate the masticatory system first.
