Headache caused by a traumatic injury to the head (e.g., headstrike, whiplash, or after a surgical craniotomy), ranging from mild trauma that causes dizziness and nausea, to trauma causing a coma. This headache does not have any defining characteristics; rather, it is classified as a trauma headache if it develops within 7 days after the injury, after regaining consciousness, or after going off pain medication that may have prevented headache symptoms in the person. If the headache lasts more than 3 months it is classed as a persistent trauma headache, rather than an acute trauma headache.
Headache is one of the most common symptoms following a head injury. However, it is important to differentiate between a general post-traumatic headache, and concussion symptoms. The following resources include more information about concussion and head trauma.
