Complex regional pain syndrome can be difficult to explain because the pain may be severe even after the original injury looks as though it should be healing. That mismatch often leaves the injured person feeling doubted by family members, insurers, and sometimes even medical providers. CRPS is a recognized chronic pain condition, but it requires careful clinical evaluation and a well-documented history.
What is complex regional pain syndrome?
CRPS usually affects an arm, hand, leg, or foot after an injury to tissue or a nerve. The National Library of Medicine describes it as a chronic condition that can cause intense pain, temperature or color changes, swelling, joint stiffness, extreme sensitivity, and reduced movement. Symptoms may worsen rather than resolve with rest and time.
The condition is commonly divided into two types. CRPS I occurs without a confirmed direct nerve injury. CRPS II follows a known nerve injury. The distinction matters medically, but both types can involve pain that is out of proportion to the expected course of the original trauma.
The MedlinePlus CRPS overview is a useful starting point, and the National Health Service (NHS) provides a more detailed explanation of symptoms and treatment approaches.
Symptoms that deserve prompt medical attention
CRPS is not simply a high pain score. Clinicians look for a pattern of symptoms and observed signs. The pattern can change over time, which is one reason repeated examinations may be important.
- Burning, throbbing, or deep aching pain that persists or grows worse
- Pain from light touch, clothing, air movement, or temperature changes
- Swelling or stiffness in the affected area
- Skin that becomes unusually warm, cold, red, pale, blue, or blotchy
- Changes in sweating, hair growth, nail growth, or skin texture
- Weakness, tremor, reduced range of motion, or difficulty using the limb
These symptoms can have other causes. A person should not diagnose CRPS from an online checklist. New or worsening symptoms after an injury should be discussed with a qualified clinician, especially when pain is interfering with walking, sleep, dressing, work, or ordinary contact with the skin.
How CRPS is diagnosed
There is no single blood test, scan, or nerve study that establishes CRPS. Diagnosis is primarily clinical. A provider considers the history, the nature and distribution of pain, reported symptoms, and signs observed during examination. Testing may be used to rule out fractures, infection, vascular disease, nerve compression, or another explanation.
Many specialists use the Budapest clinical criteria. In general terms, those criteria look for continuing disproportionate pain along with symptoms and examination findings from categories involving sensation, temperature or skin color, sweating or swelling, and movement or tissue changes. The criteria are more specific than saying that pain continued after an injury.
A normal early image does not prove that CRPS is absent. At the same time, severe pain alone does not establish the diagnosis. A thoughtful evaluation should address competing explanations and record the basis for the clinician’s conclusion.
Treatment is individualized
CRPS treatment often combines rehabilitation with pain management. Depending on the patient, clinicians may consider physical or occupational therapy, medications, psychological support for coping with chronic pain, nerve blocks, or other procedures. No single treatment works for everyone.
The practical goal is not merely to lower a number on a pain scale. Treatment also focuses on preserving or regaining movement and the ability to use the affected limb. Patients should follow the treating clinician’s plan and discuss setbacks rather than forcing activity or stopping care based on general internet advice.
Why the medical timeline matters in an injury claim
When CRPS follows a crash, fall, burn, surgery, or workplace injury, the legal dispute often centers on causation. An insurer may accept that the original injury happened while disputing whether the later pain syndrome came from that event. The medical record should therefore show how symptoms developed, what providers observed, which other conditions were considered, and how function changed.
Useful records can include:
- The first description of the injury and immediate symptoms
- Follow-up notes showing changes in pain, swelling, skin color, or temperature
- Specialist examinations and the criteria used for diagnosis
- Dated photographs of visible changes
- Physical or occupational therapy measurements
- Work restrictions and records of missed time
- A simple log of tasks the person could and could not perform
A functional log should be concrete. Recording that a sleeve could not be tolerated, a shoe could be worn for only ten minutes, or a hand could not grip a steering wheel is more informative than repeating the same pain score every day.

Be accurate about good days and bad days
Chronic pain can fluctuate. A person may complete an activity one day and pay for it with greater pain or reduced function afterward. That does not mean every photograph, social-media post, or short video is misleading. It does mean that public statements can be taken out of context.
The best protection is accuracy. Do not exaggerate limitations, but do not minimize them to appear resilient. Tell medical providers what you can do, how long you can do it, whether you needed help, and what happened later. Consistency between the medical chart, work records, and everyday account of function is more persuasive than polished language.
Louisiana claim considerations
A CRPS diagnosis does not decide fault. A Louisiana claim still requires proof that another person’s conduct caused the original injury and that the condition and losses are legally connected to it. The date of the injury also controls which filing and comparative-fault rules apply.
For injuries sustained on or after July 1, 2024, Louisiana Civil Code article 3493.1 generally provides a two-year prescriptive period for delictual actions. Accidents before that date can be governed by a different deadline. Claims involving an employer, government entity, defective product, or other special circumstance may raise additional rules, so no one should rely on a general deadline without checking the facts.
When to speak with a lawyer
A legal consultation may be useful when a serious pain condition follows an event caused by someone else, particularly if video, equipment, vehicle data, or witness information could disappear. The lawyer’s role is not to diagnose CRPS. It is to preserve liability evidence, understand the medical opinions, and present the documented effect of the condition without overstating what the records prove.
