Also called CRPS, reflex sympathetic dystrophy, RSDS, CRPS type I, causalgia (CRPS).
Complex regional pain syndrome can support SSDI or SSI when SSA finds a medically determinable impairment under SSR 03-2p and the functional limits rule out sustained work. A pain score, a Google search of CRPS, or a nerve-block trial is not an approval. SSA looks for clinical signs over time, the precipitating injury or surgery, and how the limb can actually be used.
What is Complex Regional Pain Syndrome?
NINDS describes CRPS as chronic pain, usually in an arm or leg, that typically follows injury or surgery. Type I occurs without a confirmed nerve injury; type II (causalgia) follows a nerve injury. Signs can include allodynia, swelling, temperature or color change, and dystrophic skin or nail changes. Course varies. Some people improve; others develop lasting motor neglect, contracture, or spread. There is no single laboratory test.
Common symptoms of Complex Regional Pain Syndrome
- Severe pain often out of proportion to the original injury
- Allodynia or hyperalgesia in the affected limb
- Swelling, color, or temperature change
- Abnormal sweating, hair, or nail growth
- Weakness, tremor, or reduced use of the limb
How can Complex Regional Pain Syndrome affect a person’s ability to work?
- Inability to use a hand or foot for gripping, keyboarding, standing, or operating pedals
- Off-task time from pain, allodynia from clothing or temperature, or sleep loss
- Need to elevate or protect the limb
- Absences for pain clinic, blocks, physical therapy, or mental-health care
- Safety limits around machinery when a limb cannot be used reliably
Does Social Security have a Listing for Complex Regional Pain Syndrome?
Social Security does not currently have a listing dedicated solely to Complex Regional Pain Syndrome. That does not mean a person cannot qualify. SSA may evaluate related manifestations under another listing or continue the sequential evaluation and assess residual functional capacity.
SSR 03-2p states that RSDS/CRPS is not a listed impairment, so CRPS alone cannot meet a listing. Adjudicators compare documented findings with pertinent listings for possible medical equivalence and evaluate related mental disorders under 12.00 when those independent criteria are met. The ruling describes persistent pain typically out of proportion to the precipitant plus clinically documented signs in the affected region, such as swelling, autonomic skin-color or temperature change, or abnormal hair or nail growth, at any time after the precipitant. Current musculoskeletal listings 1.18 or neurologic listings may be analogous only when their own criteria are supported—not because CRPS is named in those listings.
SSA applies SSR 03-2p to decide whether CRPS is medically determinable. Because there is no CRPS listing, the agency then considers medical equivalence to a closely analogous listing and, if not equaled, RFC including pain-related physical and mental limits. Combined impairments such as the original fracture, neuropathy, or depression are considered together.
Can you qualify if you do not meet an SSA Listing?
Yes. Most CRPS claims that succeed do so through RFC after SSR 03-2p establishes the impairment, sometimes with medical equivalence.
What medical evidence may help document Complex Regional Pain Syndrome?
- Examinations documenting autonomic or dystrophic signs, not only pain scores
- A clear precipitant (injury, surgery, or immobilization) and timeline
- Pain-clinic, neurology, or physiatry records over time
- Therapy notes about limb use, guarding, and temperature intolerance
- Mental-health records when mood or trauma symptoms are treated
Testing, imaging, and laboratory studies
- No laboratory test establishes CRPS for SSA purposes
- Bone scan, thermography, or QSART only when used in the clinical workup; they are not a listing
- Nerve studies when type II or a competing neuropathy is evaluated
Medication, physical therapy, sympathetic blocks, spinal cord stimulation, and mental-health treatment should be dated with response. Failure to complete therapy needs an explanation in the record, not only a statement that the person “could not tolerate PT.”
How SSA may evaluate residual functional capacity
RFC is often about whether the person can use the affected extremity on a sustained basis, including contact, temperature, and production pace. Do not assume CRPS always spreads or always equals amputation-level function.
Handling, fingering, reaching, standing, or pushing/pulling with the affected limb should track serial examinations.
Concentration and adaptation may be reduced by documented pain and sleep loss. A separate mental listing requires its own criteria.
Common issues that can weaken a disability claim involving Complex Regional Pain Syndrome
Pain complaints without documented signs; calling CRPS a Blue Book listing; or ignoring improvement after therapy.
What may strengthen the medical documentation
Serial examinations with objective signs, a precipitant timeline, and concrete limits on limb use during a work-like day.
Complex Regional Pain Syndrome and related medical conditions
- Carpal Tunnel Syndrome — Carpal tunnel syndrome has no dedicated adult listing. SSA evaluates documented median-nerve impairment and whether hand use, pain, or treatment recovery prevent sustained work.
- Fibromyalgia — A medically determinable impairment under SSR 12-2p when diagnostic criteria are documented. There is no fibromyalgia listing.
- Major Depressive Disorder — Persistent depressive symptoms may be evaluated under Listing 12.04. A diagnosis does not guarantee benefits; SSA also examines severity, duration, and work-related function.
- Osteoarthritis — Joint cartilage wear that can limit standing, walking, or use of the hands. SSA may consider Listing 1.18 when a major joint meets current criteria.
- Peripheral Neuropathy — Damage to peripheral nerves that may cause pain, numbness, weakness, or balance problems. Listing 11.14 applies only when its specified functional criteria are met.
How Brock & Stout may help
We develop SSR 03-2p medical-sign evidence, compare findings with analogous listings only when supported, and present limb-use RFC. Representation cannot guarantee approval.
Frequently asked questions
No current adult listing is dedicated to CRPS or RSDS. SSR 03-2p explains how SSA establishes the impairment and then considers medical equivalence or residual functional capacity.
SSR 03-2p focuses on clinical signs and a precipitant. Imaging may support the workup but is not a substitute for documented signs and lasting work-related limits.
