CRPS & Chronic Pain Claims: Why They're Fought So Hard

A wrist fracture heals. Six months later the hand is still burning, the skin has changed color, and light touch is unbearable. Complex regional pain syndrome is one of the few conditions where a claim’s real value can vastly exceed what the original injury suggested — and precisely because of that mismatch, it is among the most aggressively contested claims in personal injury.

Quick answer: CRPS is a chronic pain condition, usually in a limb, where pain becomes disproportionate to the original injury and persists past normal healing, with objective changes in temperature, color, swelling or sweating. It has no single definitive test — diagnosis is clinical, against criteria such as the Budapest Criteria. Insurers contest it on three fronts: causation (the triggering injury looked minor), legitimacy (pain is subjective), and permanence. Value is driven by permanence and lost earning capacity, not by past medical bills — which means the multiplier method understates these claims badly.

Illustrative Settlement Ranges

These are illustrative rather than predictive, and the spread is wider here than for most injuries for a specific reason: the same diagnosis can mean a claimant who recovered substantially or one who is permanently disabled, and the difference between those two outcomes is the entire claim.

Why the Claim Is Contested on Three Fronts

1. Causation. CRPS frequently follows an injury that looked minor — a wrist or ankle fracture, a crush injury, sometimes a relatively modest soft tissue injury or a surgical procedure. The disparity between a modest event and a catastrophic outcome is itself the argument the defense makes: that something this severe cannot have come from something that small.

The answer is medical, not rhetorical. Disproportionate pain relative to the inciting injury is a recognized feature of the condition, not an anomaly that undermines the diagnosis. A treating specialist stating that explicitly is worth more than any argument counsel can construct.

2. Legitimacy. Because pain is the presenting symptom and there is no single confirmatory test, insurers argue exaggeration, secondary gain, or a purely psychological origin. This is where objective findings do disproportionate work — see below.

3. Permanence. Since some cases improve, the defense position is routinely that this one will too, and that the claim should be valued as temporary. Time and documented trajectory are what answer this, which is why settling early is so risky here.

What Actually Proves It

A diagnosis documented explicitly against recognized criteria. The Budapest Criteria, adopted by the International Association for the Study of Pain, require a combination of reported symptoms and objectively observed signs across four categories — sensory, vasomotor, sudomotor/edema, and motor/trophic — with no other diagnosis better explaining the presentation. A chart that says “CRPS” is weaker than one that walks through the criteria and records which signs were observed on examination.

The objective signs, recorded on examination. These are what defeat the “it’s all subjective” framing, and they need to be in the record rather than merely reported by the patient:

• Temperature asymmetry between the affected and unaffected limb
• Skin color changes — mottling, redness, pallor
• Edema — measurable swelling
• Sweating changes in the affected area
• Trophic changes — altered hair or nail growth, skin texture change
• Allodynia — pain from light touch that should not be painful
• Reduced range of motion, weakness, tremor or dystonia

Supporting diagnostic work, which does not confirm the diagnosis on its own but corroborates it: response to a sympathetic nerve block, bone scan findings, thermography, and — for Type II specifically — nerve conduction studies documenting the nerve injury.

Specialist involvement. A pain management specialist or neurologist carries more weight on this diagnosis than a generalist, and referral timing itself becomes part of the record.

Why the Multiplier Method Gets This Wrong

The multiplier method — economic damages times a factor — badly understates CRPS claims, and for a structural reason. Past medical bills for a conservatively managed CRPS case can be modest while the future is where the value sits:

• Lifetime pain management — medication, injections, therapy over decades
• Interventional treatment — spinal cord stimulator implantation, with subsequent revisions and battery replacements
• Lost earning capacity where the claimant cannot return to their occupation, which is frequently the single largest component
• Home and vehicle modification, and personal assistance in severe cases

This puts CRPS valuation in the same category as spinal cord injury and severe traumatic brain injury claims: built from life-care planning and economic projection, not from a multiple of past bills. Our guide to how insurers calculate settlements explains why claims software reading past specials will systematically undervalue exactly this profile.

The Psychological Component

Chronic, unremitting pain commonly produces depression, anxiety and sleep disruption. Medically these are expected sequelae. In a claim they are compensable consequences of the injury — see our guide to PTSD and emotional distress settlements for how psychological damages are documented and valued.

Expect the defense to invert this: to argue the psychological findings show the pain is imagined rather than that the pain caused the psychological findings. Providers documenting the sequence — pain first, psychological effects following as consequences — is what answers it.

Practical Steps

1. See a specialist early — pain management or neurology — and get the diagnosis documented against recognized criteria.
2. Ask that objective signs be recorded on examination, not merely noted as patient-reported.
3. Do not settle before the trajectory is clear. This is the central timing risk: resolving a permanent condition at the value of a temporary one is irreversible.
4. Document functional loss concretely — specific tasks, specific work limitations, specific daily activities lost.
5. Get a written permanency and prognosis opinion once the picture stabilizes.
6. Expect a defense medical examination and understand its report will likely contest the diagnosis.
7. Have future care costed properly — a life-care plan, not an estimate — because that is where the claim’s value actually lives.
