In CRPS presentation, how long must the severe pain persist past tissue damage?

• A. 1 month
• B. 3 months
• C. 6 months
• D. 12 months

Answer: (C)

In Complex Regional Pain Syndrome (CRPS), the defining characteristic is the persistence of severe pain that is disproportionate to the extent of tissue injury. The current understanding and diagnostic criteria indicate that for a diagnosis of CRPS to be considered valid, symptoms must persist for at least 6 months beyond the initial tissue damage or injury. This timeframe is critical because it helps distinguish CRPS from other acute pain syndromes that may resolve more quickly. Long-term pain post-injury, such as exceeding the 6-month threshold, supports the diagnosis of CRPS, as the pain mechanism alters, creating a complex interaction involving both the nervous and immune systems. Recognizing this 6-month duration is essential in clinical practice for appropriate diagnosis and treatment planning. Thus, 6 months serves as a critical marker for practitioners to identify and manage CRPS effectively.
