Understanding CRPS: Why Diagnosis Can Be Difficult and How to Build a Care Plan

When pain continues long after an injury, or a light touch feels unbearable, it can be frightening, exhausting, and difficult to explain. For people with complex regional pain syndrome (CRPS), getting answers can be a challenge of its own.

At Light Therapy Resource, this subject is personal. Our founder, Sandra Burkhart, lives with CRPS and has experienced how profoundly it can affect daily life. That experience informs our commitment to helping people understand their options and become informed, proactive participants in their care.

What is Complex Regional Pain Syndrome?

CRPS is a pain condition that usually affects an arm, hand, leg, or foot, often following an injury or surgery. The pain is more intense or lasts longer than expected for the original injury.

Symptoms can include burning pain, sensitivity to touch or temperature, swelling, changes in skin color or temperature, unusual sweating, stiffness, weakness, and changes in hair, nails, or skin. Symptoms may fluctuate, and some people experience symptoms beyond the original area.

CRPS involves changes in how the nervous system processes pain, alongside inflammatory and other biological changes. Its exact mechanisms are still being studied. It is a real medical condition, not a sign that someone is exaggerating.

Type I occurs without a confirmed injury to a specific nerve; Type II involves an identified nerve injury. Both deserve careful evaluation and treatment. [1]

Why is CRPS so hard to diagnose?

There is no single blood test, scan, or nerve test that confirms CRPS. Diagnosis relies on a medical history, examination, and assessment of whether another condition better explains the symptoms. Tests may help rule out problems such as infection, a blood clot, or a different nerve disorder. [2]

Clinicians commonly use the Budapest criteria. These assess continuing pain that is disproportionate to the original event, reported symptoms across at least three of four categories, and observable signs in at least two categories. The categories cover sensation, skin temperature or color, swelling or sweating, and movement or tissue changes. Another diagnosis must not better explain the findings. [3]

Symptoms can change between appointments, which makes a thorough history especially useful. Photos of swelling or color changes and a brief symptom diary can help explain what happens outside the examination room. Normal test results alone do not mean the pain is imaginary. [1,2]

What treatment options are available?

CRPS care usually combines treatments rather than relying on one intervention.

Physical and occupational therapy help restore movement and everyday function. Treatment may include gradual activity, desensitization, graded motor imagery, or mirror therapy when appropriate. Progression should be individualized; overly aggressive rehabilitation can worsen symptoms. [3]

A prescribing clinician may consider medicines for nerve pain, topical treatments, or selected anti-inflammatory treatments. Some people also discuss sympathetic nerve blocks, ketamine infusions, spinal cord stimulation, or dorsal root ganglion stimulation with a pain specialist. These options have different risks, benefits, and levels of evidence. [1,3]

Psychological support can also help with coping, sleep, fear of movement, and the emotional burden of persistent pain. Receiving that support does not mean CRPS is psychological or that the pain is your fault. [4]

Why we place Scrambler Therapy high on the list

At Light Therapy Resource, Scrambler Therapy is high on our list of options to discuss early with appropriate candidates, alongside medical care and rehabilitation.

Scrambler Therapy is a noninvasive modality delivered through electrodes placed on the skin. Its proposed mechanism is to provide non pain information through sensory nerves, with the aim of changing persistent pain signaling.

Published CRPS case reports and a small case series describe substantial pain relief and improvements in function. These findings are encouraging, but CRPS-specific evidence remains limited. Scrambler Therapy has not been established as the best treatment for everyone or as a guaranteed cure. [5]

This emphasis reflects our founder’s lived experience and our approach to complementary support; it is not a universal ranking from CRPS treatment guidelines.

For some people, Scrambler Therapy can be an extremely effective part of a broader care plan. When pain becomes more manageable, that may create an opportunity to tolerate movement, participate in rehabilitation, and return to everyday activities. The practical goal is to connect symptom relief with improved function.

Our approach emphasizes coordinating Scrambler Therapy sessions with an appropriate rehabilitation plan developed by a qualified physical or occupational therapist, alongside carefully selected complementary modalities. Depending on individual needs, we may discuss red and near-infrared light therapy, relaxation practices, or other nervous-system support. Research on these complementary approaches for CRPS is still developing, so we personalize their use based on individual needs, tolerance, and response.

What should you do after a CRPS diagnosis?

Seek coordinated care promptly. Ask for a clinician experienced in CRPS and a physical or occupational therapist who understands the condition. Early treatment is encouraged, but a longstanding diagnosis does not mean improvement is impossible. [2,4]

Build a plan with clear goals. Track more than a pain score: sleep, walking, hand use, sensitivity, and daily activities can show whether your care plan is helping.

Discuss Scrambler Therapy early. Ask about provider experience, suitability, realistic expectations, cost, and how sessions will coordinate with your medical and rehabilitation team.

Use gradual, supported movement. Your therapist can help find a starting point and adjust progression to your response. [4]

Review and adapt. Tell your team about flares, side effects, and changes in function. Review medications with your prescriber rather than stopping them independently.

A CRPS diagnosis can feel overwhelming, but it does not define your future. You deserve to be believed, to understand your choices, and to have a plan that supports both relief and everyday life.
