The lesser occipital nerve (LON) is commonly injected alongside the greater occipital nerve for headache disorders.
Anatomy
The lesser occipital nerve (LON) arises from the primary ventral rami of the second and third cervical nerves. It passes superiorly along the posterior border of sternocleidomastoid. It divides into cutaneous branches that supply the lateral portion of the posterior scalp.

Procedure

- Locate the LON by going two-thirds of the way between the occipital protuberance and the mastoid process.
