SPG Block For Headache Treatment
Sphenopalatine Ganglion nerve block (SPG Block) is a non-invasive technique we perform in office that takes less than five minutes to address the source of your headache pain. How does it work? It targets the largest group of nerves surrounding the brain cavity, called the nasal ganglion.

What You Should Know
It’s important to note that SPG Block is not a cure for chronic headaches, but is a non-narcotic solution to relieve headache pain. A local anesthetic is administered through a unique nasal applicator to reach the nasal ganglion nerve cluster behind the nose and near the throat. The “block” prevents the signals from being delivered to the brain, so the feeling of pain is no longer processed.
The applicator consists of a soft, flexible plastic delivery tube that can easily reach the rear of the nasal cavity where the Spehnoplalatine ganglion is located. Once the small tube is gently inserted through the nostril, we can then spray the anesthetic into the sinus cavity, resulting in immediate relief from your headache. In most cases, the pain fully subsides within 10 minutes.
Initial treatment usually lasts for several hours, but for chronic headaches, we recommend a four week-program, because treatments are cumulative, which means many patients see better results after each successive treatment. However, true headache relief comes from identifying the original cause and source of the headache and working from there.
Note: A contraindication for this treatment is Lidocaine allergy.
