What is the condition characterized by chronic pain following a serious injury?

The condition characterized by chronic pain following a serious injury is complex regional pain syndrome (CRPS). This syndrome typically occurs after an injury, surgery, stroke, or heart attack and is marked by prolonged pain that is often disproportionate to the original event. CRPS may involve a variety of symptoms, including severe pain, changes in skin color and temperature, swelling, and abnormal sweating in the affected area.

The hallmark of CRPS is that the pain persists well beyond the expected recovery time and can even spread to other areas of the body. This condition is believed to involve a malfunctioning peripheral and central nervous system, leading to an exaggerated response to the initial injury. Early diagnosis and intervention are crucial in managing CRPS effectively and preventing its progression into a more chronic state.
