How do they do a nerve block for migraines? A medical professional will apply an anesthetic to the back of your head just above your neck. They’ll then insert a fine needle into the injection site until the needle reaches your occipital nerve. After the injection, the area will become numb as the pain-relieving medication takes effect.
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.
What are the side effects of an occipital nerve block? Are there any side effects caused by an occipital nerve block? The most common side effect is pain at the site of injection. Other side effects include infection, bleeding, dizziness, weakness, numbness and lightheadedness. These effects are temporary and often last only six to eight hours.
Can nerve blocks make migraines worse? Because the nerve is still conducting signals, the migraine pain worsens rather than improves. This can also happen if the injection needle comes into contact with the nerve, again causing a worsening of the distressful nerve signals rather than an improvement.
