What Are the Types of Complex Regional Pain Syndrome?
Complex Regional Pain Syndrome (CRPS) is classified into two main types: CRPS Type 1 and CRPS Type 2. CRPS Type 1, previously known as Reflex Sympathetic Dystrophy (RSD), occurs without a direct nerve injury. This type often follows a minor injury, surgery, or immobilization and is characterized by pain and sensory abnormalities that cannot be explained by a single nerve’s dysfunction. In contrast, CRPS Type 2, formerly called Causalgia, involves a confirmed nerve injury. Both types share similar symptoms, such as persistent pain, swelling, and changes in skin color or temperature, but the distinction lies in the presence or absence of identifiable nerve damage.
Understanding these types is essential for determining the appropriate management approach. Both forms can result in significant discomfort and disability, but their progression and response to therapies may vary. Early diagnosis and intervention are crucial to prevent complications and mitigate long-term effects. While the exact cause remains uncertain, research suggests that abnormal responses in the nervous system and inflammatory processes play pivotal roles in both types.
