Algoneurodystrophy: Understanding Complex Regional Pain Syndrome (CRPS)
Have you ever heard of Complex Regional Pain Syndrome (CRPS)? This rare and often misunderstood medical condition can turn a minor injury into persistent, disabling pain. Let’s find out what CRPS is, how it’s diagnosed and what treatment options are available.
“What is SDRC?”
CRPS, also known as reflex sympathetic dystrophy (RSD), is severe chronic pain, often disproportionate to the initial injury. It usually affects one limb and can lead to changes in the skin, muscles, bones and even blood circulation. This condition is classified into three types:
- Type I: No specific nerves are damaged, but symptoms are present.
- Type II: A nerve lesion is identifiable, accompanied by neuropathic pain.
- Type III: A more controversial form in which some symptoms persist despite partial remission.
“What are the signs and symptoms?”
CRDS can manifest as:
- Intense, continuous pain, often described as a burning sensation.
- Swelling, changes in skin color or temperature.
- Joint stiffness and difficulty moving.
- Abnormal sensations such as allodynia (pain provoked by a normally painless stimulus).
Why do some people develop CRDS?
CRDS is often triggered by fracture, surgery or even minor trauma. However, other factors can play a role, including:
- Gender: Women are more affected than men.
- Age: It is most common in adults aged 50 to 80, but can also affect children.
- Psychological history: Anxiety, depression or post-traumatic stress disorder (PTSD) can increase risk.
How is CRDS diagnosed?
Diagnosis is based primarily on the **Budapest criteria**, which include:
- Persistent pain disproportionate to the triggering event.
- Clinical signs in at least two categories, such as sensory, vascular, sudomotor or motor changes.
- Exclusion of other possible causes of symptoms.
Treatments : A multidisciplinary approach
The management of CRDS often requires a combination of treatments:
- Functional rehabilitation: Gentle exercises and therapies such as mirror therapy can help restore function.
- Medication: Anti-inflammatories, antidepressants or bisphosphonates may be used depending on the case.
- Nerve blocks: Stellar blocks, for example, can relieve pain by blocking nerve signals.
- Psychological support: Cognitive and behavioural therapies help manage the emotional aspects of pain.
In some cases, interventions such as spinal cord stimulation or ketamine infusions may be considered.

Hope for patients
CRDS can be a harrowing experience, but advances in research and management now offer hope to patients. A personalized approach and regular follow-up can greatly improve their quality of life.
If you or a loved one is affected by CRDS, don’t hesitate to consult a specialist. Managing this complex condition requires a dedicated, well-informed team.
