In short
- CRPS causes severe, disproportionate limb pain with swelling, colour, temperature and skin changes; it is poorly understood and has no quick cure.
- Early recognition and early referral matter most — starting physiotherapy-led rehabilitation sooner gives the best chance of improvement.
- Care is team-based: education, physical rehabilitation, pain relief and psychological support, delivered by a specialist pain service.
- Outlook varies: the NHS estimates around 85% of people slowly improve over the first 2 years, but a minority have long-term, disabling pain.
A plain-English summary. The detail — including risks and recovery — is below.

What is complex regional pain syndrome (CRPS) management?
Complex regional pain syndrome (CRPS) is a condition in which a limb — usually an arm, hand, leg or foot — becomes intensely painful, often far out of proportion to any injury. The pain is usually accompanied by changes such as swelling, colour and temperature changes, sweating, changes to skin, hair or nails, and difficulty moving the limb. It often follows an injury, surgery or even a minor knock, but sometimes there is no obvious trigger.
CRPS is poorly understood. There is no single test that proves it and no quick cure. It is diagnosed from the pattern of symptoms and by ruling out other causes. Because it is uncommon and looks like other conditions, it can be missed or diagnosed late.
Management is specialist and team-based. UK guidance from the Royal College of Physicians emphasises four strands working together: education and self-management, physical rehabilitation (usually physiotherapy-led), pain relief, and psychological support. The single most important factor is early recognition and early referral, because starting rehabilitation sooner gives the best chance of improvement.
The honest goal is to reduce symptoms, keep the limb moving and protect function and quality of life. Many people improve over time, but a minority are left with long-term, disabling pain, and being clear about this from the start is part of good care.
Types, options & approaches
There may be different ways to do this. The right approach depends on the clinical question and your circumstances.
Options at a glance
These are the main approaches described in this guide. The right option depends on the diagnosis, your goals and what your clinician thinks is safe.
Education and self-management
Understanding what CRPS is and is not, learning that gentle movement is safe and important despite the pain, and learning techniques to manage flare-ups and protect daily...
Physical rehabilitation (physiotherapy and occupational therapy)
The core of treatment. Graded movement, desensitisation, and sometimes specialised techniques such as mirror therapy or graded motor imagery, delivered by therapists...
Pain relief medicines
Medicines chosen for nerve-type pain are used carefully and reviewed; no single drug works for everyone, and medicines are an aid to rehabilitation rather than the main...
Psychological support
Help with the distress, fear, low mood and sleep problems that severe ongoing pain causes. This supports rehabilitation and is not a suggestion the pain is imagined.
Preparing for your treatment
- Write down when the symptoms started, any injury or surgery beforehand, and how the limb and pain have changed since.
- Note the changes you have seen — swelling, colour, temperature, sweating, skin, hair or nail changes, and difficulty moving the limb.
- List all medicines and treatments already tried and how they affected you.
- Think about the impact on your work, sleep, mood and daily activities, and what you most want to be able to do.
- Bring any previous letters, scans or specialist opinions.
- Consider bringing someone with you, as appointments can be a lot to take in.
- Be ready to discuss feelings honestly; emotional support is a normal part of CRPS care, not a judgement.
What happens
Diagnosis is based on your history and examination, looking for the typical pattern of disproportionate pain plus changes in the limb, and on excluding other conditions. There is no single confirmatory test, so the clinician's experience matters and a specialist opinion is often needed.
If CRPS is diagnosed, you are usually referred to or seen within a specialist pain service with a multidisciplinary team. They explain the condition and set out a plan built around physical rehabilitation, with medicines, psychological support and self-management alongside.
Treatment is delivered over time rather than in a single appointment. Therapists guide gentle, graded movement and desensitisation, building up carefully because doing too much too soon can aggravate the condition. Progress is reviewed and the plan adjusted, and you should understand the realistic aims from the outset.
Is this treatment right for me?
A good consultation should explore whether it's the right choice for you now — including reasons to wait or consider something else.
May not be suitable if…
- People whose symptoms are better explained by another condition that has not yet been properly excluded.
- People seeking a single, quick cure, which does not exist for CRPS.
- Care delivered without a multidisciplinary team, which is unlikely to meet UK guidance.
- Aggressive rehabilitation or procedures pushed too early, which can flare the condition.
Delay or rearrange if…
- There are signs of infection in the limb or you feel generally unwell.
- You are in a mental health crisis that needs urgent attention first.
- A specialist procedure is planned but there is active infection, a bleeding risk or another safety concern.
- The diagnosis is genuinely uncertain and another cause needs ruling out before committing to treatment.
Alternatives to discuss
- Referral to an NHS specialist pain service, which is the usual route.
- General chronic pain management approaches where a CRPS diagnosis is uncertain.
- Treating an underlying or coexisting condition that may be contributing.
- Self-management support and reliable information while awaiting specialist input.
- A second specialist opinion if the diagnosis or plan is unclear.
Before you decide
Use this as a shared-decision checklist. The aim is not just “can this be done?”, but whether it is right for you, now, with the risks and alternatives clearly understood.
What matters most to me?
Think about symptoms, daily life, work, caring responsibilities, sport, fertility, travel, appearance and anxiety — the right choice depends on your priorities, not just the medical facts.
What are all my options?
Ask about waiting, monitoring, medicines, rehabilitation, a smaller or larger procedure, a different test, NHS referral, or a second opinion where that would help.
What would make me pause?
Active infection, pregnancy, unstable medical problems, smoking, medicines that increase bleeding, poor support at home, or feeling pressured are all reasons to slow down and get tailored advice.
What happens if I do nothing today?
For some problems, waiting is safe; for others, delay can make treatment harder. A good consultation should explain the trade-off in plain English.
Benefits
- Early, expert care gives the best chance of reducing symptoms and keeping the limb moving
- A team approach addresses pain, movement, mood and daily function together
- Helps prevent the stiffness, weakness and loss of use that come from not moving the limb
- Provides honest information and support for a frightening, poorly understood condition
- Coordinates medicines, therapy and psychological help so they work together
Risks & complications
- Pain and progress are often slow, with flare-ups along the way
- Rehabilitation can temporarily increase pain before it helps
- Medicines for nerve-type pain can cause side effects such as drowsiness or dizziness
- Frustration and low mood, which are common with severe ongoing pain
- Symptoms spreading or worsening despite treatment
- Difficulty finding a medicine that helps without unacceptable side effects
- Significant impact on work, relationships and independence
- Long-term, disabling pain and physical impairment that persists despite full treatment
- Complications from specialist procedures, where these are used
CRPS is unpredictable and not fully understood, so no one can promise a cure or a timeline. The biggest risks are delayed diagnosis and delayed rehabilitation, and treatment that is too aggressive too soon, which can flare the condition. Beware anyone offering a single 'cure' or guaranteed result. Ask who is in the team, how rehabilitation will be paced, and what the realistic aims are.
Published figures to discuss
CRPS is unpredictable and poorly understood, and outcomes vary widely between individuals. The figures below come from UK sources but are general estimates, not guarantees for any one person. Recovery depends on how early treatment starts, the severity, the limb affected and other factors, so we present cautious ranges rather than precise predictions.
| Figure | Reported range | How to interpret it | Source / confidence |
|---|---|---|---|
| Some improvement over the first 2 years | Around 85% (NHS estimate) | An estimate of people who slowly experience some reduction in pain and symptoms; the degree of improvement varies greatly and earlier treatment helps. | NHS — Complex regional pain syndromenhs.ukPublished figure |
| Long-term, disabling pain | Around 1 in 7 (RCP guidance) | A minority continue to have unrelenting pain and physical impairment, with very low quality-of-life scores. | NHS — Complex regional pain syndromenhs.ukPublished figure |
| Delayed diagnosis or immobilisation worsening outcome | Recognised risk | Early education, desensitisation and guided movement are central; prolonged protection can worsen fear and disuse. | NHS — Complex regional pain syndromenhs.ukSource-linked context |
| Spread of symptoms beyond the original limb | Uncommon but recognised | New spread should prompt reassessment of diagnosis, function and psychological support needs. | Guide sourcesClinical context |
These are literature figures, not a personalised prediction. Your own risks and likely benefits depend on your circumstances, your health, and how your care is carried out and followed up.
What happens afterwards
There is no single procedure to recover from. CRPS care is about how your symptoms respond over months, and progress is usually gradual, uneven and built through steady rehabilitation rather than a one-off treatment.
- Slow, uneven progress rather than steady improvement
- Flare-ups of pain and limb changes, especially after activity or stress
- Temporary increase in pain when starting or progressing rehabilitation
- Tiredness and low mood at times, which are normal with severe pain
- Needing to pace activity and protect sleep
Aftercare
- Keep gently moving and using the limb as your therapist guides, even though it is uncomfortable.
- Stick with rehabilitation through flare-ups rather than stopping, unless advised otherwise.
- Take medicines as prescribed and report side effects rather than stopping suddenly.
- Use the self-management and pacing techniques you are taught to handle bad days.
- Attend psychological support sessions, which help mood, sleep and coping.
- Keep all team appointments so the plan can be reviewed and adjusted.
- Tell your team promptly if symptoms spread, worsen markedly, or new problems appear.
- A named contact within the pain or rehabilitation team
- A clear, paced rehabilitation plan you understand
- A medicines list with what each is for and how to review it
- A flare-up plan for bad days
- Access to psychological support
- A realistic discussion of aims and outlook
⚠ Get urgent help if…
- Rapidly spreading or dramatically worsening pain, swelling or colour change in the limb
- Signs of infection in the limb: increasing heat, redness, fever or feeling generally unwell
- A limb that becomes cold, pale or numb in a new way, or sudden loss of movement
- Severe side effects from medicines, such as marked drowsiness, confusion or breathing problems
- Thoughts of harming yourself, or feeling unable to cope — seek urgent mental health help
- Any new symptom that frightens you or seems out of keeping with your usual pattern
Who to contact: your clinician, clinic or test provider first (keep their number to hand). For urgent advice when you can't reach them, call NHS 111. In an emergency, call 999.
General guidance — it doesn't replace the specific advice your specialist gives you.
Results & realistic expectations
A good outcome in CRPS is usually a gradual reduction in pain and limb changes, and keeping the limb working and usable, rather than complete and permanent disappearance of all symptoms. The NHS estimates that around 85% of people slowly experience some reduction in pain and symptoms over the first two years, and earlier diagnosis and rehabilitation improve the chances.
However, CRPS is unpredictable. UK guidance notes that around one in seven people continue to experience unrelenting pain and physical impairment, reporting some of the lowest quality-of-life scores in medicine. Honest care sets realistic expectations and does not promise a cure.
For many people, improvement gained through rehabilitation is maintained, though some have flare-ups and may need to return to therapy. For those with persistent CRPS, it becomes a long-term condition managed with ongoing self-management and specialist support. Plans should be reviewed as symptoms, function and life circumstances change.
Related tests, treatments or support
CRPS care combines several treatments at once — rehabilitation, medicines, psychological support and self-management — because no single one is enough. It may also run alongside treatment for the original injury or surgery that triggered it, and alongside general pain management. Specialist procedures, where used, are added within this combined plan.
Follow-up & long-term care
Follow-up is ongoing and coordinated by the specialist team, with regular reviews of rehabilitation progress, medicines and psychological support. The plan is adjusted as you respond, and onward referral or additional input is arranged if needed. You should always know who to contact between appointments and what to do if symptoms worsen.
- Continue the movement and self-management routines you are taught, as a long-term habit
- Keep a flare-up plan and use pacing to manage bad spells
- Review medicines regularly so nothing is continued without benefit
- Protect sleep, mood and general activity, all of which affect the condition
- Stay in contact with the specialist service and return promptly if symptoms change
Repeat, follow-on and what comes next
- The plan is reviewed and adjusted regularly as the condition is unpredictable.
- Medicines are often changed to find what helps with tolerable side effects, and stopped if they do not help.
- Flare-ups and setbacks are common and do not mean treatment has failed.
- Some people need to return to rehabilitation after periods of improvement.
Ask what happens if the result is unclear or needs repeating, and what is included if further tests or follow-up are needed.
What good aftercare looks like
- A named contact within the specialist team and a clear route for help between appointments.
- A paced, individualised rehabilitation plan with built-in management of flare-ups.
- Regular review of medicines, therapy and psychological support, working together.
- Honest, ongoing discussion of aims and outlook, including the possibility of persistent pain.
- A crisis plan covering both physical worsening and mental health.
What affects the cost
Costs vary a great deal between people and providers, and we don't publish prices. What matters is understanding what drives the cost and making sure your quote is complete. The main things that affect it:
- The number and length of appointments across the multidisciplinary team
- How much physiotherapy and occupational therapy is needed, and over what period
- Psychological support sessions, which are often part of care
- Medicines and the reviews needed to adjust them
- Any specialist pain procedures, which are charged separately
- Ongoing review over months, given CRPS is usually a long-term condition
- Fees for the specialist and for each member of the team involved
- How many therapy sessions are included and what further sessions cost
- Whether psychological support is included or charged separately
- The cost of medicines and review appointments
- The cost of any specialist procedures, kept separate from consultations
- How ongoing, long-term care and reviews are arranged and charged
- Cancellation and rebooking policy
On the NHS? CRPS is usually managed within NHS specialist pain services; private access is sometimes used for a quicker or second opinion, but the multidisciplinary approach is the same.
You're entitled to your total cost in writing — including reports, follow-up and what happens if the result is inconclusive — before you decide.
Consent traps and marketing red flags
These are not small details. They are often where patients lose choice, time to reflect, or realistic expectations.
Consent traps
- Being promised a cure or a fixed recovery timeline for a condition that is unpredictable.
- Being offered a single treatment or procedure as the answer, outside a team approach.
- Not being told that some people are left with long-term, disabling pain.
- Psychological support being presented as implying the pain is 'not real'.
- No clear plan for flare-ups or for who to contact when symptoms worsen.
Marketing red flags
- Claims to 'cure' CRPS or 'reset' the nervous system with one treatment or device.
- Guaranteed results or fixed recovery timelines.
- Aggressive or expensive procedures promoted as a stand-alone fix.
- Care offered without a multidisciplinary team or experienced therapists.
- Dismissing the role of rehabilitation and self-management.
Choosing a specialist safely
- Check the specialist is on the GMC Specialist Register for this area.
- Make sure they work at a CQC-registered service, and look for membership of the relevant Royal College or professional body.
- You're entitled to time to consider and to have your questions answered before you agree — the specialist who looks after you should explain it, not a salesperson.
- Be wary of pressure: time-limited offers or deposits taken before you've had time to think are red flags, not bargains.
- You're entitled to your total cost in writing — including any follow-up — before you decide.
Questions to ask your medical professional
Take this to your consultation. A good specialist will welcome every one of these.
- What makes you confident this is CRPS, and have other causes been excluded?
- Who is in my team, and how soon can rehabilitation start?
- How will rehabilitation be paced so it helps without flaring the condition?
- What are the realistic aims of treatment for me, and over what timescale?
- Which medicines are you suggesting, what are they for, and how will they be reviewed?
- What is my plan for flare-ups, and who do I contact when things get worse?
- Are you on the GMC Specialist Register for this area, and which Royal College or professional body are you a member of?
- Will you be the specialist who carries out my treatment, and who looks after me afterwards?
- What are the risks for someone like me, and how often do your own patients have a problem or need it repeated or redone?
- What does a realistic result look like — and what can this treatment not achieve?
- What are my options, including waiting, doing nothing for now, or choosing a different approach?
- Can I have written information, results and aftercare instructions in a format I can use, including any accessibility or communication support I need?
- What is the total cost in writing, including any follow-ups, and how much time do I have to decide?
