Your greater occipital nerve is responsible for most of the feeling in the back and top of your head. Irritation or inflammation of this nerve can cause headaches.
People with occipital nerve irritation often report pain starting from the base of their skull on one side of their head. The pain may extend as far as the temple, forehead, and behind the eyes.
An occipital nerve block is one of the most common procedures to provide pain relief for migraines and chronic headaches.
