Cervicogenic headache (CHA) is one of the secondary headache disorders. The prevalence of CHA was estimated to be ~4.1%, and most of the patients affected by CHA report un-resolved, recurrent throbbing pain.~it has been treated with many treatment modalities, such as the administration of medi-cines, physiotherapy, transcutaneous electrical nerve stimulation, and interventional pro-cedures. However, these treatments do not result in long-term relief for many patients and need to be repeated Pulsed radiofrequency treatment (PRF) is one of the modalities used to treat CHA~. CHA has been known to originate from the convergence of the 3 upper cervical and tri-geminal afferents, and therefore, many physicians have performed PRF targeting the upper cervical structures (occipital nerve, C2 dorsal root ganglion).~However, this results in only short-term pain relief in the posterior head, and it can lead to some complications, such as vascular and nerve injuries. Because of these limitations, we will attempt PRF targeting the mid-cervical medial branches
To detect the Clinical efficacy of pulsed radiofrequency treatment targeting the mid cervical medial branches versus greater occipital nerve for cervicogenic headache
