Reflex Sympathetic Dystrophy (RSD), now commonly classified as Complex Regional Pain Syndrome (CRPS), is a chronic and often debilitating pain condition that can significantly impact daily life. At 21st Century Pain Management, we provide advanced, evidence-based RSD and CRPS treatment in Pearland and Sugar Land, Texas, helping patients regain function, reduce pain, and improve overall quality of life.
RSD and CRPS are characterized by severe, persistent burning pain that most often affects one extremity, such as the arm, leg, hand, or foot. Unlike typical pain conditions, RSD involves dysfunction across multiple systems — including nerves, blood vessels, skin, muscles, and bones — making early diagnosis and specialized pain management critical.
Reflex Sympathetic Dystrophy is an older term used to describe what is now known as Type I Complex Regional Pain Syndrome (CRPS). This condition typically develops after a tissue injury such as a fracture, surgery, sprain, or minor trauma, even when no direct nerve injury is identified.
Patients with RSD may experience intense burning pain, swelling, temperature changes, abnormal sweating, skin discoloration, stiffness, and extreme sensitivity to touch — a condition known as allodynia. These symptoms can worsen over time if left untreated.
Types of Complex Regional Pain SyndromeType I CRPS, historically referred to as RSD, occurs after tissue injury without confirmed nerve damage. It is the most common form and can develop weeks or months following the initial injury.
Type II CRPS is associated with a known nerve injury, often caused by high-velocity trauma such as gunshot wounds or severe accidents. This form was first documented more than a century ago while studying chronic pain in Civil War veterans.
Both types share similar symptoms and require comprehensive pain management by a specialist experienced in treating complex pain disorders.
