Description: Synonyms (commonly used interchangeably although they are not strictly speaking all the same entity): reflex sympathetic dystrophy, causalgia, Sudeck's atrophy, post traumatic dystrophy, shoulder hand dystrophy, reflex neurovascular dystrophy.
In 1979, the International Association for the Study of Pain (IASP) stated that pain is “an unpleasant sensory and emotional experience associated with actual or potential tissue damage or, is described in terms of such damage” and in 1994, it went on to specify that "Pain is always subjective. Each individual learns the applications of the word through experiences relating to injuries in early life”.
CRPS is a complex and poorly understood condition. It is typically characterised by segmental limb pain after a (usually) relatively minor injury to a limb but is more severe and lasts much longer than would normally be expected given the injury. It may also encompass a range of problems involving one or more of the nerves, skin, muscles, blood vessels and bone. Occasionally, it affects parts of the body other than the limbs and it may also arise in the absence of injury. It is thought to arise as a result of abnormal sympathetic nerve healing following trauma although the exact pathophysiology still remains very much a mystery.
