OnabotulinumtoxinA Nerve Blocks in the Treatment of Occipital Neuralgia
Occipital neuralgia is characterized by severe pain, accompanied by tenderness and trigger points, in the distribution of the greater, lesser, and/or third occipital nerves. Occipital neuralgia is typi- cally idiopathic, but also is characterized as a common form of posttraumatic headache. Typical treatments include nerve blocks with local anesthetic, nerve stimulation, pulsed radiofrequency, and cryoablation. OnabotulinumtoxinA (ONA) has recently been utilized in nerve blocks to treat occipital neuralgia, with the potential for a longer duration of pain relief than local anesthetic.
