Migraine is a severe condition and causes headaches, associated with nausea, vomiting and sensitivity to light and sound. Migraines are typically caused by increased blood flow to the blood vessels in the head and also stretching of the nerves which carry pain signals to our brain.
The first of which is the trigeminal nerve, which is closely associated with the sphenopalatine ganglion. So, if we were to inject medication to the nerve, we would be able to reduce the pain and other symptoms caused by migraine. This treatment is known as Sphenopalatine Nerve Block. Similarly, there is another treatment known as Occipital Nerve Block, in which local anesthetic is injected into regions of the greater and lesser occipital nerve. Both of these are effective ways to counter headaches caused by migraines.
