Headaches are the second most common complaint following motor vehicle accidents (MVA’s). Like the many other MVA symptoms, headache may not be present immediately following the accident and may take several weeks and often months to eventually surface.

Most post-traumatic headaches are thought to originate from the soft tissues and facet joints of the neck as well as injury or irritation to the nerves of the upper cervical spine.
The literature has shown there to be multiple types of headaches which can be experienced following a MVA. These include the following:

Cervicogenic Headaches
Muscle Tension Headaches
Migraine Headaches
Myofascial Trigger Point Headaches
Site-Of-Impact Headaches
Drug-Induced Headaches (following excessive or prolonged analgesic use)
