BACKGROUND AND OBJECTIVES: According to the International Classification of Headache Disorders, post-traumatic headache is characterized by pain of variable intensity, maximum in the trauma area, which starts up to seven days after the injury. This study aimed at reporting a case of post-traumatic chronic headache, secondary to firearm injury. Pain was triggered by palpation of triggering points at the scar. CASE REPORT: Male patient, 31 years old, suffered a firearm injury at the left cervical region, developing refractory headache with maximum area at the scar region. Triggering points at the scar region were observed. A treatment with peripheral block was proposed with excellent response. CONCLUSION: It is suggested that the formation of neuromas in scar areas may be involved with the pathophysiology of post-traumatic headache.
