What Is an SPG Block?

The sphenopalatine ganglion (SPG) is a cluster of nerves located deep within the face, near the nasal cavity. These nerves play a key role in headache and migraine pain, as they are directly connected to the trigeminal nerve—the main nerve involved in migraines.

An SPG block is a simple, in-office procedure where a small amount of anesthetic (such as lidocaine) is applied to the SPG through the nose using a specialized applicator. This temporarily disrupts pain signals, providing relief from migraines and other headache conditions.

Think of it like hitting the "reset button" on your headache pain—by calming these overactive nerves, your body can break the cycle of chronic migraines.
