Occipital neuralgia, also known as C2 neuralgia, Arnold's neuralgia, is a medical condition characterized by chronic pain in the upper neck, back of the head and behind the eyes. These areas correspond to the locations of the lesser and greater occipital nerves.
Occipital neuralgia is caused by damage to these nerves. Ways in which they can be damaged include trauma (usually concussive), physical stress on the nerve, repetitious neck contraction, flexion or extension, and as a result of medical complications (such as osteochondroma, a benign tumour of the bone).
One cause is vascular compression.
The symptom of this condition is chronic headache. The pain is commonly localized in the back of head and around or over the top of the head, sometimes up to the eyebrow or behind the eye. Because chronic headaches are a common symptom for numerous conditions, occipital neuralgia is often misdiagnosed at first, most commonly as tension headache or a migraine leading to treatment failure or addiction. Another symptom is the eyes being sensitive to light, especially when headaches occur.
Once diagnosed, occipital neuralgia can be treated in several ways. These include local nerve block, peripheral nerve stimulation, steroids, rhizotomy, phenol injections, antidepressants, and Occipital Cryoneurolysis.
Other less common forms of surgical neurolysis or microdecompression are also used to treat the condition when conservative measures fail.
