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

This study looked at two types of nerve block injections used to treat people with cervicogenic headache (CEH) and occipital neuralgia (ON)-two painful conditions that often cause pain at the back of the head and neck. The injections target nerves in the upper neck that may be causing the pain. The researchers compared: One nerve injection (greater occipital nerve block, or GONB), versus Two nerve injections (GONB plus lesser occipital nerve block, or LONB).
