08 Jul Complex Regional Pain Syndrome: Causes, Symptoms, and Treatment Options
Complex Regional Pain Syndrome (CRPS) ranks among the most misinterpreted chronic pain syndromes.
It arises after injury and never fully goes away. Patients who suffer from CRPS typically experience burning pain that won’t quit, skin colour and temperature changes, and loss of movement in the affected limb.
CRPS typically occurs as a result of severe trauma — such as the trauma someone suffers in a driver fatigue truck accident. When a sleepy truck driver collides with a passenger vehicle, the resulting injuries can cause long-lasting nerve damage which turns into CRPS months later. Many victims of these accidents consult with a dedicated Virginia truck accident lawyer to help seek compensation because CRPS can be costly to treat and lasts for years.
This article covers all you need to know about CRPS, including causes and treatments.
What Is Complex Regional Pain Syndrome?
CRPS is a chronic pain condition that usually affects one limb. It’s rare — but it’s brutal.
CRPS develops after an injury, surgical procedure, or physical trauma. The pain experienced is much more severe than the initial injury would ever warrant. This contributes to why it’s difficult to diagnose. According to the National Institute of Neurological Disorders and Stroke, CRPS causes ongoing pain that is much stronger even after the underlying injury has healed.
There are two main types of CRPS:
- CRPS Type 1: Occurs after an injury in which there is no proven nerve damage (formerly known as Reflex Sympathetic Dystrophy)
- CRPS Type 2: Develops after a confirmed nerve injury
Both types cause similar symptoms. And both can be life-altering.
CRPS may be rare, but these statistics are still surprising. A Mayo Clinic study reported an incidence of 5.46 per 100,000 people per year. It occurs 4 times more often in women than men, and the median age of onset is 46.
The Real Causes of CRPS
CRPS doesn’t just appear out of nowhere. It’s almost always triggered by something.
Trauma & Physical Injuries
Trauma is the leading cause of CRPS. In one retrospective study looking at CRPS patients, direct trauma caused 75.5% of cases. This consists of fractures (especially wrist fractures), sprains and strains, crushing injuries, and amputations.
Car accidents are another massive cause. Truck accidents especially often result in the type of traumatic injuries that lead to CRPS. Drivers that are sleep deprived while operating an 80,000 pound truck can inflict serious harm on anyone who happens to be driving around them.
Daily driver fatigue accidents occur across America. The injuries victims sustain reveal themselves months later as CRPS.
Surgery
Surgery can cause CRPS as well. Sometimes even minor surgical procedures result in inflammation of nerves that leads to CRPS.
Other Triggers
Less common triggers include heart attacks, strokes, infections, and prolonged immobilisation (like being in a cast).
Common Symptoms of CRPS
The principal complaint is severe burning pain. However there is much more to it than that. CRPS symptoms include skin colour changes (red, blue, or blotchy), swelling in the affected area, skin temperature changes (hot or cold to the touch), excessive sweating, changes in hair and nail growth, joint stiffness, loss of muscle strength, and muscle spasms and tremors.
Pain can be burning, throbbing, crushing or feel like the limb is being squeezed in a vise. The pain is disproportionate to the injury itself — that is, severe pain.
Here’s what makes CRPS so tricky: symptoms can evolve over time. Early on there may be warmth and swelling. Then later the same extremity may become cold and stiff. This can lead physicians astray and cause delay in diagnosis.
It’s important to catch it early. The sooner treatment can begin, the sooner you can recover.
Treatment Options That Actually Work
There is no known cure for CRPS. However there are many options available for pain management and increasing function.
Most treatment plans combine multiple approaches. Let’s break down the main ones.
Physical Therapy
Physical therapy is usually the first line of treatment. The goal is to keep the affected limb moving. This helps with reducing pain over time, preventing muscle atrophy, improving flexibility, and maintaining range of motion.
It hurts — moving that limb causes pain. But it’s important to keep going because it greatly improves prognosis.
Medications
Doctors prescribe several types of medications for CRPS, including NSAIDs to reduce pain and inflammation, corticosteroids to reduce inflammation in early stages, anticonvulsants to calm nerve pain (like gabapentin), antidepressants for nerve pain and mood support, and opioids for severe pain (used carefully).
Treatment options are individualized. The optimal combination of medications will vary depending on where the patient is in their CRPS course and how they respond.
Nerve Blocks
Sympathetic nerve blocks are injections of anaesthetic next to the affected nerves. Blocks can provide temporary relief of symptoms and may also be used to confirm the diagnosis.
Spinal Cord Stimulation
An alternative treatment for those who aren’t responsive to other therapies is spinal cord stimulation. A device sends mild electrical pulses to the spinal cord which prevents pain messages from reaching the brain. It’s not a cure, but it can change the lives of patients who have debilitating CRPS.
Psychological Support
Living with chronic pain can seriously damage mental health. Therapy and counselling options are available to help patients cope with depression, anxiety, sleep problems, and relationship stress. Cognitive behavioural therapy (CBT) has been shown to be especially helpful for CRPS patients.
Final Thoughts
CRPS is a serious condition that can change lives in an instant. Every year fatigued truckers cause horrific accidents, and victims are left suffering from chronic pain conditions like CRPS long after the accident has happened.
To quickly recap: CRPS is a chronic pain condition triggered by trauma; symptoms include burning pain, swelling, and skin changes; treatment usually combines physical therapy, medication, and other approaches; and early diagnosis leads to significantly better outcomes.
Don’t hesitate to take action if someone you love suffers from CRPS due to a truck accident. Seeking medical and legal assistance can greatly benefit your recovery.
Living with CRPS can be extremely difficult. However if patients find the appropriate treatment plan and support system they can return to function and reclaim their quality of life.
