Quick Summary:

• Complex Regional Pain Syndrome (CRPS) is a chronic and progressive condition that often affects the arms, hands, legs, or feet. It usually develops after an injury, surgery, stroke, or a heart attack
• The condition is characterized by pain that is usually disproportional to the severity of the injury. CRPS is 3-times more likely to occur in women, than men
• The exact cause is unknown, however, researchers believe that an abnormal functioning of the affected nerves, or dysfunction of pain perception in the brain, may be possible causes
• CRPS is an uncommon disorder, in which an individual may have intense pain, alteration of skin color, swelling, and temperature change of the affected region. In many cases, the pain may be felt in regions, away from the site of injury. E.g. an individual, who suffers an injury to the right leg, may experience pain in the left leg
• Treatment of CRPS is more successful, if it is started early, especially if the signs and symptoms are mild. In individuals, who have severe signs and symptoms, the recovery is often slower. In others, the signs and symptoms can worsen over time, leading to long-term disability

There are 2 types of Complex Regional Pain Syndrome:

• Type 1 occurs following an injury or illness, which did not directly injure any nerves surrounding the affected extremity. A high percentage of individuals, who develop Complex Regional Pain Syndrome, have Type 1 CRPS
• Type 2 CRPS occurs after a confirmed distinct nerve injury

The signs and symptoms of both Type 1 CRPS and Type 2 CRPS are similar.
