Complex Regional Pain Syndrome (CRPS) is a chronic pain condition that most commonly affects one limb after an injury, surgery, stroke, or heart attack. It is characterized by intense, prolonged pain that is disproportionate to the initial injury, along with symptoms such as swelling, changes in skin color and temperature, and abnormal sweating in the affected area. The precise cause of CRPS is not fully understood, but it involves abnormal responses in the nervous system. This debilitating condition can severely impact daily life and emotional well-being, making effective management and treatment crucial for improving the quality of life for those affected.
