Nerve block vs. Botox for chronic migraine
Treatments studied
Part of Brain & nervous system, Pain clinical trials.
This study compares two treatments for chronic migraine: a nerve block (sphenopalatine block) and Botox injections. It aims to see which one works better for reducing headache days.

This study compares two treatments for chronic migraine: a nerve block (injection near the nerves in the head) and Botox injections. It aims to see which one works better to reduce headache days and improve quality of life.
This Phase 3 study compares two headache injections—Botox and Xeomin—for people with chronic migraine. It may help find out which option works better to reduce frequent, long-lasting migraine days.
This study tests whether a nerve block injection near the neck (called stellate ganglion block), guided by ultrasound, can reduce chronic migraine pain. It may be a good option if you have chronic migraine and haven't found relief from standard preventive medications.
This trial tests if Xeomin (a botulinum toxin injection) can help prevent chronic migraine. If you have frequent migraine headaches, you may be able to join.
This trial tests two treatments—botulinum toxin injections and nerve blocks in the neck—to reduce migraine frequency in people who have migraines on 15 or more days per month. Either or both treatments may help prevent migraines.
This study tests two power levels of a pulsed radiofrequency treatment aimed at a nerve cluster behind your cheekbone to reduce chronic migraine pain. If you have frequent migraines that haven't responded well to two or more preventive medications, this could be an option for you.
