Disability Benefits for Complex Regional Pain Syndrome (CRPS)

How SSA Evaluates CRPS

Complex regional pain syndrome (CRPS), once called reflex sympathetic dystrophy, is a chronic pain condition that usually follows an injury and produces pain far out of proportion to the original event. There is no dedicated Blue Book listing for CRPS, but SSA recognizes it as a genuine impairment in its own Social Security Ruling, which explains how to document and evaluate it.

How SSA Approaches Your Claim

Because there is no listing to meet exactly, most CRPS claims are decided through a residual functional capacity assessment or by comparing the condition to a related listing. SSA looks for a diagnosis supported by the objective signs that define CRPS, including:

• Swelling in the affected area.
• Skin color or texture changes — for example, mottled, red, or shiny skin.
• Temperature differences between the affected limb and the rest of the body.
• Abnormal sweating, changes in hair or nail growth, or tremor in the affected area.

SSA weighs how long these signs persist and how consistently they appear in your records, since CRPS symptoms can vary from day to day. Because the condition is defined largely by pain, SSA gives real weight to the credibility of your reports and to whether the medical evidence supports them. A steady treatment history and statements from your doctors describing your limitations are especially important. If CRPS has caused lasting joint stiffness or contractures, SSA may also consider the affected joint under the musculoskeletal listings.

Medical Evidence for a CRPS Claim

Because CRPS has no listing and no single confirming test, a detailed, consistent record is what carries a claim. SSA will look for:

• A clear diagnosis from a doctor, ideally a pain specialist or neurologist, with the objective signs of CRPS noted on exam.
• Documented physical signs — swelling, skin color and temperature changes, altered hair or nail growth, and sensitivity to touch.
• Treatment history — nerve blocks, physical therapy, medications, or spinal cord stimulation, and how you responded.
• A consistent pain record describing location, intensity, and how symptoms limit your daily activities.

Ask your doctor to describe how CRPS affects your ability to stand, walk, grip, and use the affected limb, and how pain interferes with concentration and stamina. Because the diagnosis rests heavily on your reports, consistent visits and matching descriptions across your records make your claim far more credible.

Qualifying Through an RFC Assessment

Most CRPS claims succeed through the residual functional capacity (RFC) assessment, which measures the most you can still do despite your pain. When CRPS affects an arm or hand, it can severely limit gripping, lifting, typing, and fine manipulation, sometimes to the point that the limb is barely usable. When it affects a leg or foot, it limits standing, walking, and balance, and may require a cane or other device.

Beyond the affected limb, constant pain and the strong medications used to treat it reduce concentration, disturb sleep, and drain stamina, keeping many people off task or absent. Extreme sensitivity to touch, temperature, or vibration can rule out many work settings. SSA combines these limits into an RFC and compares it to your past jobs. If you cannot return to that work, the medical-vocational grid rules may direct a finding of disabled, particularly for claimants age 50 and older limited to sedentary work.

Tips for a Stronger CRPS Claim

• See a pain specialist or neurologist. A specialist diagnosis with documented objective signs makes CRPS far more credible to SSA.
• Make sure the physical signs are recorded. Swelling, color and temperature changes, and skin changes should appear in your exam notes, not just your own descriptions.
• Keep a pain and symptom journal and share it with your doctor so day-to-day variation is captured.
• Describe functional limits. Explain how pain affects using the limb, standing, gripping, sleeping, and concentrating.
• Stay in continuous treatment, since gaps in care are a common reason pain-based claims are denied.
