Scar pain may occur after an operation, and can result in chronic pain in and around the scar area.
The cause of scar pain is damage to a small skin nerve, or when a nerve is squeezed by the scar tissue. With scar pain, which can occur after an operation, there is a neuroma formation at the end of a damaged skin nerve. After some interventions, such as inguinal hernia, lung, heart, kidney, and shoulder operations, as well as breast amputations, scar pain is more common.
Patients with scar pain typically complain of neuropathic pain, during which continuous pain is present, alternating with spontaneous attacks of stabbing pain in the scar area. This pain can sometimes occur after a complaint-free period lasting some months postoperatively.
