Cervicogenic headaches are headaches that originate as a result of neck pain. They are most commonly as a result of cervical facet arthritis and secondarily the associated muscle related pain. Increased tone in the muscles that support the neck cause the tension at the attachment site and this contributes to the pain. Poor posture is also a common culprit of pain because of the muscle imbalances and muscle related pain. The combination of all these imbalances can result in headaches. Once the diagnosis is made clinically, precision guided nerve blocks are diagnostic tests that are performed to identify which part of the neck is the source of the pain. This is the first step toward achieving relief of the pain.
