The prevalence of Complex Regional Pain Syndrome (CRPS) is estimated to range from approximately 5 to 26 cases per 100,000 people, though these figures vary widely due to significant challenges in clinical diagnosis. Epidemiology and Demographics While data on the exact incidence of Complex Regional Pain Syndrome is limited, studies suggest an annual incidence of approximately 5 to 29 cases per 100,000 person-years. It is widely considered a rare condition, though its true prevalence may be higher than recorded statistics indicate.
14 people with CRPS Complex Regional Pain Syndrome have shared their first-person experience on this question at DiseaseMaps.
What is the prevalence of CRPS Complex Regional Pain Syndrome?
Prevalence of CRPS Complex Regional Pain Syndrome: how many people are affected worldwide, differences by sex and region, with sources.
The prevalence of Complex Regional Pain Syndrome (CRPS) is estimated to range from approximately 5 to 26 cases per 100,000 people, though these figures vary widely due to significant challenges in clinical diagnosis.
Epidemiology and Demographics
While data on the exact incidence of Complex Regional Pain Syndrome is limited, studies suggest an annual incidence of approximately 5 to 29 cases per 100,000 person-years. It is widely considered a rare condition, though its true prevalence may be higher than recorded statistics indicate. CRPS shows a clear gender predilection, with women being affected three to four times more frequently than men. While it can occur at any age, including in pediatric populations, the average age of onset typically falls between 40 and 60 years.
Challenges in Data Collection
Accurately mapping Complex Regional Pain Syndrome is difficult due to the lack of a single diagnostic "gold standard" test. Many patients endure long periods of misdiagnosis or underdiagnosis, as symptoms can overlap with other neuropathic or musculoskeletal conditions. Furthermore, there is currently no robust evidence linking the prevalence of CRPS to specific geographic or ethnic populations, though research remains ongoing. Because of these diagnostic hurdles, clinical registries often report conservative numbers that may not capture the full scope of the patient population.
Real-World Perspectives
Complementing clinical literature, the DiseaseMaps.org community provides a vital, real-world perspective. With 1,998 members currently sharing their lived experiences, this platform highlights the global reach of Complex Regional Pain Syndrome and the urgent need for better diagnostic tools and awareness. Connecting with others through such communities can provide invaluable support for those navigating the complexities of this condition.

Female:male ratio was 4:1, with a median age of 46 years at onset.
Upper limb was affected twice as commonly as lower limb. All cases reported an antecedent event and fracture was the most common trigger (46%).
The National Institutes of Health have estimated that 2-5% of people who have a peripheral nerve injury (such as a sprain or fracture, bullet wound, cut or needle stick) will develop CRPS.

Its more common in adults but children tend to respond best to treatment.
