Complex Regional Pain Syndrome (CRPS) is a chronic pain condition that usually affects an arm or a leg, often following an injury, surgery, stroke, or heart attack. The pain experienced is typically disproportionate to the original injury and can be severe, burning, or throbbing. CRPS is believed to involve dysfunction in both the peripheral and central nervous systems, causing abnormal responses to pain signals. In addition to intense pain, the affected area may show changes in skin color, temperature, and texture, and may become swollen or sensitive to touch.
CRPS can also affect movement and function. The affected limb may become stiff, weak, or prone to spasms, and in some cases, the joints may begin to stiffen or deteriorate over time. The condition can fluctuate, with periods of increased symptoms followed by relative calm, and it can have a significant impact on daily activities, emotional well-being, and quality of life. Because it is complex and variable, CRPS is often challenging to understand and diagnose, requiring careful attention to the combination of pain, sensory changes, and functional
limitations.
