What Is Complex Regional Pain Syndrome (CRPS) and What Causes It?
Complex Regional Pain Syndrome (CRPS) is a chronic pain condition that typically develops after an injury or trauma to a limb. The pain experienced in CRPS is often disproportionate to the initial injury, and it can continue long after the injury has healed. The exact cause of CRPS is not fully understood, but it is believed to be related to abnormal responses of the nervous system. CRPS is thought to involve both the peripheral and central nervous systems, where an initial injury leads to an exaggerated response of the body's pain-processing mechanisms. This can result in ongoing pain, swelling, and changes in skin color and temperature in the affected area.
