Do nerve blocks work for migraines? Nerve blocks are a common treatment option for migraine headaches. During the procedure, a medical professional injects a nerve-numbing substance around specific nerves in order to stop them from sending signals to the brain. This can stop a person from experiencing pain associated with migraine headaches.
How often can you get a nerve block for migraines? Overall, occipital nerve blocks seem to be a relatively effective pain management option. People with chronic headache pain generally get three to four injections per year. It’s rare to get more than three in a 6-month period. The more injections you get, the higher your risk is of having steroid-related side effects.
Can you drive after a migraine nerve block? After an occipital nerve block, a patient can usually drive home and return to normal daily activities the following day. The effects of the local anesthetic may wear off in a few hours, but the effects of the steroid begin to increase over the next several days.
How long does a cranial nerve block last? The local anesthetic will wear off in 4 hours. At that time, your usual level of pain may return until the steroid starts working. This can take up to 2 weeks. Pain relief from an occipital nerve block usually will last for several months, but this may vary from patient to patient.
