THE CLINICAL SYNDROME
\
SIGNS AND SYMPTOMS
\
TESTING
There is currently no diagnostic procedure available for analgesic rebound headache.
Magnetic resonance imaging (MRI) of the brain and, if significant occipital or nuchal symptoms are present, magnetic resonance imaging (MRI) of the cervical spine should be performed on all patients who have recently experienced the onset of chronic daily headaches that are thought to be analgesic rebound headaches.
In patients who had previously stable tension-type or migraine headaches but who have recently seen a change in the severity of their headache symptoms, an MRI should also be conducted.
If the diagnosis of analgesic rebound headache is uncertain, screening laboratory tests, which include a complete blood count, erythrocyte sedimentation rate, and automated blood chemistry, should be conducted.
