What is Arnold’s Neuralgia?
Arnold’s Neuralgia, also known as Arnold’s Syndrome or Arnold’s Headache, is a condition characterized by intense pain along the occipital nerve (also known as the Arnold nerve), located at the back of the neck and head. This occipital nerve can become irritated or compressed, causing sharp, burning, or tingling pain.
The Arnold nerve originates from the second cervical root, located between the first and second vertebrae of the neck (C1 and C2). It ascends along a path to the top of the skull, where it ends in the scalp.
During its course, this nerve crosses three muscles responsible for various movements of the head: the inferior oblique muscle of the head (or large oblique), the superior oblique muscle of the head (or small oblique), and the rectus capitis posterior major muscle.
These muscles, crucial for various head movements, play a key role in the complexity of anatomy. Their proximity to the Arnold nerve creates a situation where it can become irritated or compressed, thus contributing to the manifestations of Arnold neuralgia. We have two of these nerves, one on each side of the head.
It is also important to note that Arnold’s neuralgia is not considered a migraine, but is indeed a type of headache.
