Complex Regional Pain Syndrome (CRPS) is a chronic pain condition that develops after an injury, surgery, or trauma, and it can turn a straightforward personal injury claim into something far more complicated. The pain is severe, persistent, and wildly out of proportion to whatever caused it. If you’ve broken a wrist in a car accident and three months later your entire hand is burning, swollen, and hypersensitive to touch, that’s the kind of outcome CRPS produces.
CRPS is a chronic neuropathic pain condition that typically affects one limb following an injury or surgery. It causes burning pain, swelling, skin changes, and motor dysfunction that far exceeds the severity of the original trauma. Roughly 200,000 new cases are diagnosed annually in the United States alone, according to the National Institute of Neurological Disorders and Stroke (NINDS, 2026).
I’ve worked on content for personal injury firms across Australia for years, and CRPS cases are some of the most contested claims in the system. Insurers dispute the diagnosis. Defence medical experts argue the pain is exaggerated. And most people living with CRPS don’t even realise they have it until months after the initial injury, which makes proving causation a genuine fight.
This article won’t cover every rare pain condition or general chronic pain management. It focuses specifically on CRPS, how it affects personal injury claims in Western Australia, and what you need to do if you suspect you have it.
What Is Complex Regional Pain Syndrome?
CRPS is a disorder of the peripheral and central nervous systems. It happens when nerve signalling goes haywire after trauma, creating inflammation, pain, and changes in skin temperature, colour, and texture that don’t match the severity of the original injury.
You might also see it referred to as Reflex Sympathetic Dystrophy (RSD), Causalgia, or Sudeck’s Atrophy. These are older names for what the medical community now classifies under one umbrella. The condition usually hits one arm, hand, leg, or foot, though in roughly 10–20% of cases it spreads to the opposite limb.
The medical community still doesn’t fully understand why some people develop CRPS and others don’t. A 2025 meta-analysis published in Anesthesia & Analgesia found a pooled 12-month prevalence of 3.04% in populations who’d experienced trauma or surgery. That’s not a small number. If you’ve had a fracture, a deep laceration, or even routine surgery like a knee arthroscopy, CRPS is a real possibility.
What Are the Two Types of CRPS?
| CRPS Type I | CRPS Type II | |
| Also known as | Reflex Sympathetic Dystrophy | Causalgia |
| Nerve damage | No confirmed nerve lesion | Confirmed nerve injury |
| Frequency | About 90% of cases | About 10% of cases |
| Proving causation | Harder (no identifiable nerve damage) | Easier (nerve injury is documented) |
| Typical settlements (AU/US data) | $100k–$500k+ if well-documented | $500k–$2M+ with strong evidence |
Type I is far more common, but it’s also far harder to prove in court because there’s no clear nerve lesion to point to. Type II cases, where a specific nerve injury is documented, give your legal team stronger ground to establish a direct link between the incident and your condition.
Is CRPS Considered a Disability in Australia?
It can be. If CRPS prevents you from working and your symptoms have persisted beyond 12–18 months with medical evidence supporting functional loss, it may qualify as a disability. The new ASIPP diagnostic criteria released in July 2025 now specifically address chronic CRPS (Budapest criteria met for 12 months or more), which gives claimants better clinical backing for disability arguments. The growing recognition of CRPS at a government level, including a 2025 U.S. House bipartisan resolution designating November as CRPS Awareness Month, also helps establish legitimacy in medicolegal settings.
What Triggers CRPS After an Injury?
CRPS most commonly follows a physical injury to a limb. The trigger doesn’t need to be severe. A simple wrist fracture, a deep cut from a motor vehicle accident, or surgery for carpal tunnel syndrome can all set it off.
The most common triggers include fractures (particularly of the arm or wrist), penetrating injuries from accidents, post-surgical complications, crush injuries, and sprains. Less commonly, CRPS can follow a stroke, heart attack, or spinal cord injury.
CRPS typically appears 4–6 weeks after the triggering event. And here’s a point most articles skip. The condition affects upper limbs more often than lower limbs. If you’ve broken your arm in a workplace accident and the pain hasn’t faded after six weeks, don’t assume it’s normal healing. Push for a referral.
How Do You Recognise CRPS Symptoms?
CRPS often flies under the radar because the symptoms overlap with normal post-injury pain. You assume your hand still hurts because you broke it. But the pain isn’t fading. It’s getting worse. That’s your first warning sign.
Physical signs: Burning, throbbing pain in the injured limb. Pain that fluctuates in intensity. Loss of fine motor control (struggling to grip a pen, inability to make a fist).
Nerve and sensory changes: Tremors, stiffness, increased sensitivity to touch or temperature. Some people report that even a light breeze across the skin of the affected limb causes severe pain.
Skin, hair, and nail changes: The affected limb may feel warmer or colder than the opposite side. Skin might become dry or excessively sweaty. Nail growth and hair growth patterns change. These asymmetric signs are actually useful for diagnosis. The Cleveland Clinic provides a thorough overview of these symptoms and treatment options that’s worth reading if you want more detail.
Psychological impact: Living with unrelenting pain takes a toll. Depression, anxiety, sleep disruption, and feelings of desperation are common. These psychological symptoms are compensable in a personal injury claim and they significantly affect your quality of life.
How Is CRPS Diagnosed in Australia?
CRPS diagnosis relies on the Budapest Criteria, developed by the International Association for the Study of Pain. Your doctor will assess how many symptoms you have, their severity, and whether the pain is disproportionate to the original injury.
In July 2025, the American Society of Interventional Pain Physicians (ASIPP) published the first time-based criteria for chronic CRPS, requiring Budapest criteria to be met for 12 months or longer. This is a significant development. It gives treating specialists and medicolegal experts a standardised way to confirm that CRPS isn’t just acute post-injury pain but a long-term condition.
Here’s the contrarian take most articles won’t give you. The Budapest Criteria are good for clinical diagnosis, but they’re not always enough for litigation. Insurers routinely argue that CRPS is subjective or psychosomatic. If you’re building a claim, you need a pain specialist with experience in both diagnosing CRPS and providing evidence for court. A GP’s opinion alone won’t cut it.
Seek medical advice as soon as possible. If you suspect CRPS, ask for a referral to a qualified pain specialist who regularly treats the condition. Early intervention within 3–6 months of onset gives you the best chance of blocking the pain signals before they become permanent.
What Treatment Options Exist for CRPS in 2026?
There’s no single cure. Treatment is multimodal, meaning multiple therapies run in parallel. The goal is pain reduction, functional improvement, and preventing the condition from becoming chronic and progressive. The RSDSA’s 2025 conference reinforced the value of multidisciplinary care approaches combining physical rehabilitation, pain management, and psychological support.
| Treatment | Approximate Cost (AUD) | Notes |
| Physiotherapy and occupational therapy | $5,000–$15,000 initial | First-line treatment. Most effective when started early. |
| Medication (gabapentinoids, ketamine infusions) | $10,000–$30,000/year | Offers faster relief but carries side effects and tolerance risks. |
| Spinal cord stimulator implant | $50,000–$80,000+ | Manufacturers report 70–80% relief. Forum users report higher revision rates (20–30%). |
| Cognitive behaviour therapy (CBT) | $3,000–$8,000/year | Addresses the psychological burden. Often underutilised. |
A Swiss cohort study (cited 2025) found that healthcare costs roughly double after a CRPS diagnosis, with average insurance payments hitting approximately $86,900 USD plus $23,300 in direct treatment over five years per patient. That’s 13–19 times higher than non-CRPS cases. If you’re settling a claim, your solicitor needs a life-care plan that accounts for these long-term costs.
Many people aren’t diagnosed with CRPS for years, which means they live with worsening symptoms and weakened legal positions. The most expensive mistake in a CRPS case is waiting.
Can You Claim Compensation for CRPS in Western Australia?
Yes. If your CRPS developed because of someone else’s negligence, you may be entitled to compensation. The type of claim depends on how the triggering injury happened.
You could pursue a workers’ compensation claim if the injury occurred at work. If a car accident caused the initial trauma, a motor vehicle claim applies. Injuries in public places may fall under public liability. And if CRPS developed following surgery, you may have grounds for a medical negligence claim.
If you’re already partway through a personal injury claim and suspect CRPS, raise it with your solicitor immediately. Once a claim settles, pursuing additional compensation for a CRPS diagnosis that comes to light afterwards is extremely difficult. In most cases, you won’t get a second chance.
Under Western Australian law, you should also be aware of limitation periods. The statute of limitations typically runs from the date of injury, but for CRPS, where symptoms develop weeks after the initial trauma, the date of diagnosis can matter. Early legal advice protects your position.

FAQs
What is the average settlement for CRPS in a personal injury claim?
There’s no universal average. CRPS settlements vary widely based on severity, evidence quality, and jurisdiction. Well-documented Type I cases with permanent disability have settled between $100,000 and $500,000. Type II cases with confirmed nerve injury frequently reach $500,000 to $2 million or more. A 2025 Nevada case involving CRPS from a slip-and-fall resulted in a $15 million verdict.
Can you sue for CRPS after surgery in Australia?
Yes, if the surgery was performed negligently and your CRPS is causally linked to that surgical error. You’ll need a pain specialist’s diagnosis using the Budapest Criteria and expert testimony confirming the connection. Recent cases include settlements exceeding $2 million for post-surgical CRPS.
How do you prove CRPS in court?
Clinical diagnosis via the Budapest Criteria is the baseline. The 2025 ASIPP chronic criteria (Budapest met for 12+ months, asymmetric findings, sensory changes) strengthen your case. Objective tests like quantitative sensory testing and intraepidermal nerve fibre density biopsy can provide additional evidence. A qualified pain specialist’s testimony is non-negotiable.
Is CRPS a permanent disability?
Often yes, when symptoms persist beyond 12 to 18 months with documented functional loss. The ASIPP’s 2025 diagnostic guidance for chronic CRPS now provides a clinical framework for establishing permanence. Permanent disability status increases both non-economic damages and future care awards in personal injury claims.
How long after an injury can CRPS develop?
CRPS typically appears 4 to 6 weeks after the triggering injury. In Western Australia, limitation periods generally run from the injury date, but the date of diagnosis can be relevant for CRPS. Early reporting to your doctor and solicitor is important for establishing causation.
Can CRPS spread to the other limb?
Yes. Clinical reports indicate CRPS becomes bilateral in roughly 10 to 20% of cases. Spread to the opposite limb increases the total impact on your daily function and can significantly raise the value of a personal injury claim through higher future care and loss-of-capacity calculations.
