CRPS, or Complex Regional Pain Syndrome, is what was formerly known as RSD. CRPS is a pain disorder and considered to be permanent, or as medical professionals often refer to it: “chronic”. There are several ways a person can develop Complex Regional Pain Syndrome. CRPS can be sustained through an obvious physical injury such as a surgical error (in cases of Medical Malpractice, to which CRPS-II has a direct link), or can be sustained in an accident such as a car or motorcycle crash. Regardless of how a person develops the condition, it’s considered to be one of the most excruciating, permanent diseases a person can suffer from.
