Best Treatments for Complex Regional Pain Syndrome (CRPS) in 2026

Complex regional pain syndrome (CRPS) causes severe, persistent pain that far exceeds the original injury. The condition has a reported annual incidence of 5.5 to 26.2 per 100,000, most commonly following a fracture or surgery. Women are three to four times more likely to develop CRPS than men, with peak incidence in adults over 50.

What makes CRPS so difficult to treat is its underlying mechanism. In the acute phase, inflammation and sympathetic nervous system dysfunction drive pain signals. But when CRPS persists beyond the initial injury, the nervous system itself undergoes changes that sustain pain beyond injury. The ASIPP's 2025 multidisciplinary guidelines now recognize chronic CRPS as involving nociplastic pain, meaning the brain and spinal cord amplify danger signals even after the original injury heals. This shift in understanding has reshaped treatment priorities. The nine approaches below are organized by current evidence strength, starting with the one that targets this root cause.

Key Takeaways

• CRPS involves nervous system changes (central sensitization) that sustain pain beyond the original injury, and the ASIPP 2025 guidelines now CRPS as nociplastic pain.
• Behavioral and neuroplastic pain therapy, including CBT and pain reprocessing techniques, targets the brain and nervous system mechanisms that maintain chronic CRPS.
• Graded motor imagery and mirror therapy have CRPS-specific trial evidence showing meaningful pain improvement in adults with CRPS type I.
• Multidisciplinary programs combining physical rehabilitation, psychological intervention, and medical management are recommended as the standard of care by the ASIPP 2025 guidelines and RSDSA fifth edition.
• Lin Health's approach is based on findings from neuroplastic pain research, applying behavioral retraining to address the nervous system changes that drive persistent pain conditions like CRPS.

1. Behavioral and Neuroplastic Pain Therapy

The ASIPP's 2025 multidisciplinary guidelines identify psychological intervention as one of four treatment pillars, alongside education, pain relief, and physical rehabilitation. This reflects a growing consensus that chronic CRPS is not just an inflammatory condition. Once the acute phase resolves, the pain often becomes centrally maintained, sustained by sensitized neural circuits, fear-avoidance patterns, and emotional responses to pain.

What It Is

Behavioral and neuroplastic pain therapy uses structured techniques to interrupt the nervous system patterns that keep pain active after tissue healing. The most evidence-supported modalities include:

• Cognitive behavioral therapy (CBT): Identifies and reshapes thought and behavior patterns that amplify pain. A 2025 systematic review found CBT-informed neurocognitive interventions to be an important for CRPS management across all treatment phases.
• Pain reprocessing therapy (PRT): Trains the brain to reinterpret chronic pain signals as non-dangerous. In adults with chronic primary back pain, PRT produced lasting pain relief at five years in a randomized trial, compared to 26% receiving placebo.
• Emotional awareness and expression therapy (EAET): Addresses the emotional drivers of chronic pain. A 2025 meta-analysis of three trials found that meaningful pain reduction, compared to 17% receiving standard CBT alone.
• Acceptance and commitment therapy (ACT): Builds psychological flexibility around pain. A 2024 meta-analysis of 21 trials showed medium effect sizes in adults with chronic pain.

Lin Health combines CBT, ACT, somatic tracking, and pain neuroscience education into a coach-led, app-supported program. The approach is based on findings from this body of neuroplastic pain research. A 2026 review in Current Pain and Headache Reports named PRT, EAET, and graded exposure among the brain-centered nociplastic interventions that target central sensitization directly.

Why It Ranks First

Two factors set behavioral approaches apart for CRPS specifically. First, chronic CRPS is now formally recognized as involving nociplastic pain mechanisms, which are the exact targets of these therapies. No other treatment category directly addresses the brain's role in sustaining pain after tissue healing. Second, the evidence for long-term durability is stronger here than for medications or nerve blocks. PRT's five-year follow-up showed that treatment gains persisted without maintenance therapy, a result that pharmacological approaches have not matched for chronic primary pain.

Who It's For

Adults with CRPS lasting beyond three months, especially those who notice pain worsening with stress, fear of movement, or emotional distress. Also appropriate for people who have cycled through medications and procedures without sustained improvement. Lin Health is covered by most major insurance plans in Colorado, Texas, Florida, California, and New York. Most enrolled patients pay nothing out of pocket.

2. Graded Motor Imagery and Mirror Therapy

Graded motor imagery (GMI) is one of the few treatments with CRPS-specific randomized trial evidence. It works by gradually re-engaging the brain's motor and sensory maps for the affected limb, which research shows become disrupted in CRPS.

What It Is

GMI follows a three-stage protocol:

1. Left/right limb recognition: The patient views photos of hands or feet and identifies whether each is left or right. This activates the premotor cortex without triggering pain.
2. Imagined movements: The patient mentally rehearses moving the affected limb without actually moving it, activating motor planning areas at a lower intensity.
3. Mirror therapy: The unaffected limb is moved in front of a mirror, creating a visual illusion that the affected limb is moving painlessly. This retrains body representation.

Why It Works

A 2024 systematic review of six randomized trials (171 participants) found GMI and mirror therapy improved pain scores on a 100-point scale in people with CRPS type I, with concurrent functional improvements. Sample sizes remain small, so the evidence is promising rather than definitive.

The approach directly addresses cortical reorganization, one of the hallmarks of CRPS. Brain imaging studies show that CRPS patients have altered somatosensory cortex representations of the affected limb, and GMI appears to normalize these patterns.

Who It's For

Adults with CRPS type I affecting an extremity, particularly those who experience pain with movement or have developed fear of using the affected limb. GMI can be done at home after initial instruction and complements both behavioral therapy and physical rehabilitation.

3. Physical and Occupational Therapy

The ASIPP 2025 guidelines recommend progressive physical therapy and first-line CRPS rehabilitation for CRPS. The goal is functional restoration, not pain elimination.

What It Is

CRPS-specific PT and OT typically include:

• Desensitization: Gradually exposing the affected area to different textures, temperatures, and pressures to reduce allodynia and hypersensitivity
• Graded exposure in vivo: A structured protocol where patients progressively attempt feared movements, breaking the cycle of avoidance that worsens outcomes
• Functional task training: Rebuilding the ability to use the affected limb in daily activities, from gripping a cup to typing on a keyboard
• Edema management: Compression, elevation, and manual lymphatic drainage to reduce the swelling common in acute CRPS

Why It Works

Physical rehabilitation prevents the deconditioning and limb disuse that worsen CRPS outcomes. Immobilization and avoiding the affected limb reinforce the brain's association between movement and danger, a pattern that both physical therapy and behavioral approaches work to break. The combination of exercise with CBT shows the strongest evidence for CRPS rehabilitation overall.

A 2024 Dutch randomized trial evaluated graded exposure in vivo against standardized physiotherapy for CRPS type I patients with pain-related fear, reflecting the trend toward psychologically informed physical rehabilitation.

Who It's For

All CRPS patients benefit from physical rehabilitation, regardless of stage or subtype. Early and consistent engagement is critical. Working with a therapist experienced in CRPS is important, as overly aggressive PT can cause flare-ups while overly cautious approaches miss the therapeutic window.

4. Multidisciplinary Pain Rehabilitation Programs

Both the RSDSA's fifth edition treatment guidelines and the ASIPP 2025 guidelines recommend multidisciplinary rehabilitation as the standard approach for CRPS. These programs combine multiple treatment modalities under coordinated care.

What It Is

A multidisciplinary CRPS program typically brings together physical therapy, occupational therapy, psychological support (CBT, pain education), and medical management, delivered by a coordinated team. Programs may run as intensive outpatient (several hours per day, multiple days per week) or inpatient for severe cases.

Why It Works

Coordinated care addresses CRPS from multiple angles simultaneously. A 2024 inpatient interdisciplinary treatment study found improvements across disease severity, depression, anxiety, physical function, and pain interference measures. The rationale is straightforward: CRPS involves physical, neurological, and psychological components, so treating only one dimension rarely produces lasting change.

However, access can be a barrier. Intensive multidisciplinary programs require significant time, travel, and sometimes out-of-pocket cost. Virtual and coach-led options like Lin Health can fill part of this gap by delivering the behavioral and educational components remotely, with insurance coverage.

Who It's For

People with moderate-to-severe CRPS who have not responded adequately to individual treatments. Particularly valuable for those dealing with significant functional disability, mood disturbance, or symptoms lasting more than a year.

5. Medications

Pharmacological treatment for CRPS focuses on managing symptoms rather than reversing the underlying condition. Several drug classes have evidence, though limited medication evidence.

Gabapentinoids

Gabapentin and pregabalin are commonly prescribed for the neuropathic pain component of CRPS. A 2025 meta-analysis of 14 studies found pregabalin slightly superior to gabapentin in pain reduction and quality of life. Prescribing is largely based on broader neuropathic pain guidelines, not CRPS-specific trials.

Bisphosphonates

Neridronate has the strongest pharmacological evidence for CRPS. A 2024 study of 103 CRPS type I patients showed intravenous neridronate reduced pain significantly at 12 months, with hyperalgesia resolving in 84% and allodynia in 88%. Benefits were maintained up to three years. Early treatment, lower-limb CRPS, and male sex predicted the strongest responses. Neridronate is approved for CRPS in Italy but is not currently FDA-approved in the United States.

Corticosteroids and Other Options

Short courses of oral corticosteroids may help in early CRPS (within the first 12 months), per RSDSA guidelines. Topical options include capsaicin 8% patches, DMSO 50% cream, and lidocaine 5% patches, each with low-to-moderate evidence. Antidepressants like duloxetine and amitriptyline are sometimes prescribed for the neuropathic component based on general chronic pain guidelines.

Who They're For

Medications work as adjuncts to rehabilitation and behavioral approaches, not as standalone treatments. They can help manage acute symptoms during the window when behavioral and physical therapies take effect, or address specific CRPS features like neuropathic burning or bone loss.

6. Low-Dose Naltrexone (LDN)

Low-dose naltrexone is an emerging option that has generated significant interest in the CRPS community. At standard doses (50 mg), naltrexone blocks opioid receptors. At low doses (1 to 5 mg), it appears to modulate neuroinflammation by reducing glial cell activation in the central nervous system.

What It Is

LDN is prescribed off-label for CRPS. The medication is typically compounded by a specialty pharmacy, as the low dosage is not commercially available in the United States. It is usually taken once daily at bedtime.

Current Evidence

No completed randomized trial exists for LDN in CRPS specifically. A Stanford University trial (NCT02502162) is currently recruiting, with estimated completion in July 2027. The Hospital for Special Surgery is running a separate Phase 4 trial. Published evidence comes from case series and small studies in other central sensitization conditions, including fibromyalgia and multiple sclerosis.

Who It's For

People with CRPS who have not responded to standard treatments and are comfortable with an off-label, investigational option. LDN's favorable side-effect profile makes it worth discussing with a pain specialist, but it should not replace approaches with stronger current evidence.

7. Spinal Cord Stimulation and Neuromodulation

For CRPS that has not responded to conservative treatments, neuromodulation offers measurable relief in a significant proportion of patients. This category includes traditional spinal cord stimulation (SCS) and the newer dorsal root ganglion (DRG) stimulation.

What It Is

• Spinal cord stimulation (SCS): Electrodes placed near the spinal cord deliver mild electrical pulses that interrupt pain signal transmission. A trial period (typically one to two weeks) confirms benefit before permanent implantation.
• Dorsal root ganglion (DRG) stimulation: Targets the dorsal root ganglion, a nerve cluster near the spine that processes sensory input. FDA-approved for CRPS since 2016, DRG stimulation provides more targeted coverage than traditional SCS, which can be especially valuable for focal CRPS pain in a single limb.

Why It Works

A 2024 systematic review of randomized trials confirmed that spinal cord stimulation reduces pain effectively in refractory CRPS, with sustained long-term benefit. The 2025 BOOST-DRG trial, a prospective randomized crossover study, compared SCS and DRG stimulation directly and found DRG stimulation particularly effective for focal neuropathic pain patterns.

Who It's For

Adults with refractory CRPS who have not responded to at least six months of behavioral, physical, and pharmacological treatment. Neuromodulation is a surgical intervention with risks including infection, lead migration, and hardware failure. It should be considered after less invasive options have been given adequate trial.

8. Ketamine Infusion Therapy

Ketamine, an NMDA receptor antagonist, has shown potential for severe, treatment-resistant CRPS. By blocking NMDA receptors, ketamine may help interrupt sensitized pain pathways in the central nervous system.

What It Is

Ketamine is administered intravenously in a clinical setting, typically over multiple sessions lasting several hours each. Protocols vary widely in dosage, duration, and number of sessions. An oral ketamine formulation is currently being evaluated in a clinical trial (NCT06419985).

Current Evidence

A 2025 narrative review in Current Pain and Headache Reports synthesized evidence showing significant pain reduction in refractory CRPS patients receiving IV ketamine. A 2026 case report documented complete resolution of CRPS-related dystonia with multiday intravenous ketamine infusion. However, evidence comes primarily from case series, observational studies, and small trials. No large randomized controlled trial has been completed.

Who It's For

Patients with severe, refractory CRPS who have not responded to multiple other treatments. Ketamine carries significant side effects (dissociation, nausea, elevated blood pressure, potential for misuse) and requires close medical supervision. It is not a first-line treatment.

9. Sympathetic Nerve Blocks and Interventional Procedures

Sympathetic nerve blocks have been used for CRPS for decades. They target the sympathetic nervous system, which contributes to maintaining CRPS pain in a subset of patients with "sympathetically maintained pain."

What It Is

• Stellate ganglion block: An injection of local anesthetic near the stellate ganglion in the neck, used for upper-extremity CRPS
• Lumbar sympathetic block: A similar injection in the lower back, used for lower-extremity CRPS
• Intrathecal baclofen: Delivered directly to the spinal fluid for CRPS-related dystonia, supported by earlier randomized trials

Current Evidence

Evidence for sympathetic nerve blocks is rated low to moderate in the RSDSA fifth edition guidelines. No new randomized trials have been published between 2023 and 2026. Blocks serve both a diagnostic role (confirming whether pain is sympathetically maintained) and a therapeutic one, though pain relief from individual blocks is often temporary, lasting days to weeks.

Who It's For

Adults with CRPS who show clinical signs of sympathetically maintained pain, particularly in the acute or early chronic phase. Nerve blocks are most useful when combined with physical rehabilitation during the temporary pain-reduction window they provide, allowing patients to engage more fully in therapy.

How Lin Health Helps with CRPS

CRPS often follows a frustrating trajectory. An injury that should have healed months ago continues causing pain that resists conventional treatments. The ASIPP 2025 guidelines explain why: in chronic CRPS, the pain alarm in the nervous system gets stuck. Inflammation resolves, but the brain and spinal cord continue amplifying danger signals through central sensitization.

Lin Health's approach is based on findings from neuroplastic pain research that directly target these nervous system changes. The program combines cognitive behavioral therapy, acceptance and commitment therapy, somatic tracking, and pain neuroscience education, delivered by trained recovery coaches through weekly live sessions and a between-session app. The goal is to retrain the brain's pain response, reducing its tendency to fire danger signals when no structural threat exists.

What sets Lin Health apart from general therapy:

• Specialized in persistent pain conditions: Recovery coaches are trained specifically in chronic pain and neuroplastic pain mechanisms, not general mental health
• Insurance covered: Most major plans in CO, TX, FL, CA, and NY accepted. Most enrolled patients pay nothing out of pocket.
• Short wait times: Often a same-day callback after signing up, unlike the months-long waits common in specialized pain clinics
• Coach-led, not self-paced: Weekly sessions with a real person who understands CRPS, not just an app or a book

Lin Health offers behavioral and neuroplastic pain support for CRPS, delivered by trained recovery coaches and covered by most insurance plans. Wait times are short, often a same-day call.

FAQ

Is there a cure for CRPS?

There is no single cure for CRPS. However, many people experience significant improvement or full resolution of symptoms, especially with early, multimodal treatment. The ASIPP 2025 guidelines emphasize that chronic CRPS involves nociplastic pain mechanisms that can be addressed through behavioral, rehabilitative, and medical approaches working together.

What is the most effective treatment for CRPS?

No single treatment works for everyone with CRPS. Current evidence supports a multimodal approach combining behavioral therapy, physical rehabilitation, and targeted medications. The ASIPP 2025 guidelines recommend four treatment pillars: education, pain relief, physical rehabilitation, and psychological intervention. Behavioral approaches rank highly because they target the central sensitization that maintains chronic CRPS.

Can CRPS go away on its own?

Some cases of CRPS, particularly mild ones identified early, do resolve without intensive treatment. However, chronic CRPS rarely resolves spontaneously. Population-level data show that many patients still have significant symptoms at one year, and the longer CRPS persists, the more entrenched the nervous system changes become. Early, active treatment improves long-term outcomes significantly.

What are the newest treatments for CRPS in 2026?

Several treatments have gained momentum. Dorsal root ganglion (DRG) stimulation, FDA-approved since 2016, has growing support from the 2025 BOOST-DRG trial. Neridronate, a bisphosphonate approved for CRPS in Italy, showed strong 12-month results in a 2024 study. Brain-centered interventions like PRT and EAET are increasingly recognized for nociplastic pain conditions including chronic CRPS.

Does physical therapy help CRPS?

Yes, when done appropriately. Physical therapy is recommended as first-line rehabilitation in the ASIPP 2025 guidelines. The key is working with a therapist experienced in CRPS who uses graded approaches, including desensitization and progressive functional training. Overly aggressive PT can trigger flare-ups, so careful, gradual progression is essential.

Can CRPS spread to other parts of the body?

CRPS can spread beyond the initial injury site. Research shows that some cases spread spread to other limbs. In some people, symptoms move to the opposite side of the body (mirror-image spreading). This pattern supports the central sensitization model, where the nervous system itself drives pain independent of local tissue damage.

Is CRPS a neurological or psychological condition?

CRPS is a neurological condition with important psychological dimensions. The Budapest diagnostic criteria classify it based on sensory and motor signs, and it is not "all in your head." However, the ASIPP 2025 guidelines recognize that chronic CRPS involves nociplastic pain, and psychological interventions that target the nervous system are a core treatment pillar.
