Complex regional pain syndrome is a rare type of chronic pain which usually affects an arm or a leg. In most cases, Complex Regional Pain Syndrome develops following an injury, surgical procedure, stroke or heart attack. In any cases, the pain experienced is completely out of proportion to the initial injury. Complex regional pain syndrome is still something of a mystery, and there are many things that we do not yet understand. The symptoms can last for months, or even years for some people, but for others, they will go away on their own.
Some of the common symptoms linked to complex regional pain syndrome include:
- Continuous throbbing pains or burning sensations in an arm, leg or foot
- Increased sensitivity to touch and cold
- Painful swelling in the affected area
- Sporadic changes in skin temperature
- Changes in skin color and texture
- Changes in nail and hair growth
- Stiffness in the joints
- Limited range of movement in the affected area
- Muscle spasms, weaknesses, and atrophy
Complex Regional Pain Syndrome is sometimes known as Reflex Sympathetic Dystrophy Syndrome (RSDS).
