What are nerve block injections?

Pericranial nerve block injections are a minimally invasive procedure that can be safely performed in the clinic setting. Anesthetic, such as lidocaine or bupivacaine, is injected around the nerves of the face and back of head. Nerve blocks can treat acute headache pain, including stopping a prolonged headache, or can also be used as a preventive therapy for migraine headache. 

When performed by a trained specialist, series of nerve blocks can be safely given including during times of pregnancy. 

In addition to pain relief, nerve blocks can also help improve symptoms of light sensitivity, sound sensitivity, and other bothersome symptoms related to an underlying headache disorder. Nerve blocks and trigger point injections may be used in combination for the management of migraine headache.
