In the diagnosis of cervicogenic headache, greater occipital nerve (GON), cervical nerve, minor occipital nerve, and cervical facet joint blocks are used. In our study we compared the GON and C2/C3 nerve blocks in the diagnosis and treatment of cervicogenic headache. In both cases, repeated blocks proved to have a long-lasting effect in the treatment of this disorder, with both GON and C2/C3 blocks being found to be equally effective.
