Nerve Blocks

Purath Neurology & Headache and Diamond Headache Clinic offers unique treatments for headache patients called ` nerve block treatments. This is a selection of nerve blocks such as, Nerve Occipital Nerve Block, Sphenoganglion Nerve Block and Stellate Ganglion Nerve Block. A nerve block can stop or abort chronic tension, migraine and cluster headaches. The procedure is performed by an experienced physician, the solution (anesthetic or anesthetic/steroid mixture) is injected in a small needle into the area around the nerves.

  • Occipital Nerve Block

An occipital nerve block can provide significant pain relief for some headache sufferers. It works by preventing the flow of pain signals from the occipital nerves that are causing the headache to the brain.

  • Sphenoganglion Nerve Block (SPG)
    The SPG is associated with the trigeminal nerve, which is the main nerve involved in a headache. Located deep in the face behind the nasal cavity, the sphenopalatine ganglion is a cluster of sensory and autonomic nerves. Blocking these nerves has been shown to be effective in reducing the frequency and severity of cluster and migraine headaches.
  • Supraorbital Nerve Block 

It is thought that blocking the supraorbital nerve lessens pain in the front of the head by shutting down the pain receptors in the nerve. The nerve block may also work by preventing the nerve from carrying pain information to the central nervous system. The injection site for the SON nerve block is generally in the forehead, at the eyebrow area.
