C2/C3 nerve blocks and greater occipital nerve block in cervicogenic headache treatment.

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.
