Greater Occipital Nerve Block Alone Versus Dual Nerve Block in Cervicogenic Headache and Occipital Neuralgia

A landmark-guided injection of 1 mL of 2% lidocaine administered at the anatomical location of the greater occipital nerve (GON) to treat cervicogenic headache and occipital neuralgia. Performed without corticosteroids or imaging guidance.

Two landmark-guided injections of 1 mL of 2% lidocaine each at the anatomical locations of the greater and lesser occipital nerves. Performed without corticosteroids or imaging, targeting broader nerve involvement in cervicogenic headache and occipital neuralgia.
