Decoding Pain: How Chronic Regional Pain Syndrome Challenges Medical Understanding

Imagine your body’s pain system as an alarm that is designed to warn you of danger, where some alarms are more sensitive than others. Just as fire alarms and car alarms can vary in their responsiveness, our experience of pain can be equally complex and unpredictable.

Pain is not simply the result of pain sensors being activated throughout the body. It is far more complicated, shaped by context and individual perception. Pain is processed in the central nervous system and occurs when the brain perceives actual or potential tissue damage. Interestingly, research shows that tissue damage seen on medical imaging often does not correlate with the symptoms experienced. Many people have structural changes or degeneration without feeling any pain. On the other hand, some complex pain conditions trigger the brain to signal pain as a warning of danger, even when there is no real threat or tissue damage (Butler & Moseley, 2013).

One such complex condition is Chronic Regional Pain Syndrome (CRPS), a rare condition affecting approximately 20 in 100,000 (Rose, 2023). It often follows an injury or trauma, but what makes it particularly challenging is the disproportionate level of pain in relation to the injury. Alongside this severe pain, individuals may experience changes in skin color, temperature, and swelling in the affected limb (Packham & Holly, 2018). Below is a simplified look at what CRPS is, how it’s treated, and what can be done to manage it.

What is CRPS?

CRPS can be confusing because its symptoms and the way it affects people can differ vastly. The exact cause isn’t fully understood, but experts believe it involves a mix of several mechanisms (Rose, 2023):

1. Inflammation: The body’s natural response to injury, which can sometimes go overboard.

2. Nerve Sensitivity: The nerves become extra sensitive and send pain signals more easily.

3. Changes in Brain Function: The brain’s processing of pain signals can become altered.

How does your healthcare team treat CRPS?

Treatment for CRPS aims to help you manage your symptoms and improve your quality of life. Here’s a breakdown of some common approaches:

1. Physical Therapy: This helps improve movement and reduce pain through exercises tailored to your needs which may include graded motor imagery and mirror therapy. Physical therapists will provide education to help you better understand CRPS and can use techniques to reduce sensitivity and improve function (Packham & Holly, 2018).

• Graded Exposure Therapy: This approach involves slowly increasing activity levels in a controlled manner to help you get used to movement without causing a flare-up (Noigroup, n.d.).

2. Medications: Sometimes medications are used to manage pain and inflammation. This might include pain relievers, anti-inflammatories, or nerve pain medications (Rose, 2023).

3. Psychological Support: Dealing with chronic pain can be stressful and emotionally challenging. Counselling, mindfulness, or cognitive behavioural therapy can help manage the emotional side of CRPS (Rose, 2023).

Stay Active: Gentle, gradual movement is often beneficial. Avoid complete rest, as it can make symptoms worse over time. Your Victoria physiotherapist can guide you on appropriate exercises and activities (Packham & Holly, 2018).

Manage Pain: Techniques such as warm baths, gentle stretching, massage, and relaxation exercises can help manage discomfort (Packham & Holly, 2018).

Stay Positive: CRPS can be frustrating, but keeping a positive outlook and working closely with your healthcare team can make a big difference (Rose, 2023).
