The Needle-Free SPG Block: Fast, Intranasal Migraine Relief
What Is an SPG Block?
An SPG block, short for sphenopalatine ganglion block, is a quick, gentle treatment that can stop a migraine at its source.
The sphenopalatine ganglion (SPG) is a small bundle of nerves located deep in your nose, behind your sinuses. These nerves help control pain and blood flow in the head and face—and they play a major role in migraine attacks.
When the SPG becomes overactive, it can send pain signals that trigger migraine symptoms like throbbing head pain, nausea, light sensitivity, and tearing. By calming this nerve center, an SPG block helps the body “reset,” bringing fast relief.
Think of the SPG as a light switch for head pain. When a migraine starts, that switch gets stuck in the “on” position. The SPG block gently flips it back “off.”
During the procedure, a small, soft applicator (similar to a long cotton swab) or a tiny flexible catheter is placed just inside your nostril. A numbing medicine—usually lidocaine—is delivered to the area where the SPG lives. You may feel mild pressure or a cool sensation for a few seconds. Within minutes, the numbing medicine soaks into the nerve cluster and shuts down the pain signals that drive migraine symptoms.
That’s it—no needles, no IV, and no sedation needed.
What Are the Benefits?
SPG blocks are one of the few migraine treatments that offer rapid relief and can be performed safely in just a few minutes.
Here’s why so many patients love them:
Needle-free: No injections or IVs—just a simple nasal application.
Rapid relief: Many people notice improvement within 5–10 minutes.
Safe and well-tolerated: The numbing medicine used (lidocaine) has been safely used in medicine for decades.
Drug-free option: Ideal for those sensitive to migraine medications or looking to limit prescription use.
Can be repeated as needed: Some patients benefit from occasional SPG blocks during flare-ups, while others include them in their preventive care plan.
SPG blocks can significantly reduce pain scores and shorten migraine duration for both acute and chronic migraine sufferers.
What to Expect During Treatment
Your Vale provider will have you lie comfortably while a small amount of numbing spray is applied to your nose. Then, using a soft, flexible applicator, the anesthetic is gently placed near the SPG.
The entire process takes about 5–10 minutes and feels similar to a saline rinse or nasal spray.
After a short rest period, you’ll be ready to go about your day—no downtime required. Some people experience mild throat numbness or a bitter taste for a few minutes, but these effects fade quickly.
