If you have ongoing arm or leg pain due to complex regional pain syndrome (CRPS), you don’t have to live with debilitating discomfort. At Interventional Pain Specialists of Wisconsin, SC, in Hudson, Rice Lake, and Altoona, Wisconsin, the interventional spine and pain management specialists offer advanced treatments to improve function and help restore your quality of life.
What is CRPS?
Complex Regional Pain Syndrome (CRPS) is a chronic pain condition that typically affects an arm or a leg following injury, surgery, or another triggering event. It is characterized by an abnormal response of the nervous system, leading to pain that is disproportionate to the initial injury. CRPS is classified into two main types:
- CRPS-I (formerly called reflex sympathetic dystrophy) – without confirmed nerve injury.
- CRPS-II (formerly causalgia) – associated with a distinct nerve injury.
Early detection and treatment greatly improve outcomes, and some individuals may even experience remission of symptoms.
Symptoms of CRPS
CRPS may present with a wide range of symptoms, including:
- Sensitivity to touch, temperature, or cold exposure
- Persistent throbbing, burning, or stabbing discomfort
- Pain in the arm, leg, hand, or foot
- Swelling, warmth, or redness
- Skin changes in color, temperature, or texture (shiny or thin skin)
- Joint stiffness and reduced mobility
- Abnormal hair or nail growth
- Muscle spasms, tremors, or weakness
- Affected limb feeling unusually cold or pale
If untreated, CRPS may result in permanent tissue changes, such as muscle contractures or bone loss (disuse osteoporosis). Symptoms may also spread beyond the original injury site.
What Causes CRPS?
The exact cause of CRPS remains uncertain, but it is thought to involve dysfunction in both the peripheral and central nervous systems. The condition can follow fractures, sprains, surgery, infections, or even seemingly minor trauma. Certain factors, such as nerve compression or abnormal inflammatory responses, may increase the risk. Conditions like neuropathy or previous injuries may also make some people more vulnerable.
Diagnosing CRPS
At Interventional Pain Specialists of Wisconsin, SC, diagnosis begins with a detailed history and physical exam. Specialists evaluate pain characteristics, sensory changes, and motor function. Diagnostic tools may include:
- Imaging such as X-rays, MRI, or bone scans to assess structural changes
- Autonomic testing, such as sweat output measurements
- Nerve conduction studies to rule out other conditions like spine pain or peripheral neuropathy
This comprehensive approach ensures accurate identification and guides treatment planning.
Treatment Options for CRPS
CRPS treatment is individualized and often requires a multidisciplinary approach. At Interventional Pain Specialists of Wisconsin, SC, therapies may include:
- Lifestyle guidance and physical therapy to preserve mobility and prevent stiffness
- Occupational therapy to maintain function in daily activities
- Heat therapy for circulation and comfort
- Peripheral nerve stimulation and spinal cord stimulation for targeted pain relief
- Sympathetic nerve blocks (stellate ganglion and lumbar sympathetic blocks)
- Ketamine infusions for severe or treatment-resistant CRPS
The team focuses on early and aggressive management to prevent long-term disability and to restore quality of life.

Frequently Asked Questions
Who is most at risk for developing CRPS?
CRPS most commonly affects adults aged 40 to 70 and is more common in women than in men. It often occurs after an injury, surgery, stroke, or heart attack, especially when nerve damage is involved.
Can CRPS occur without an injury?
Yes, although less common, CRPS can develop without a clearly identifiable injury. In some cases, minor trauma or even internal changes in the nervous system may trigger symptoms.
Is CRPS a lifelong condition?
CRPS is not always lifelong. Some patients experience significant improvement or remission, especially with early treatment. However, others may have persistent or recurring symptoms that require long-term management.
How serious is CRPS?
CRPS can be a serious and potentially disabling condition. It often causes chronic pain, changes in skin and bone health, and reduced mobility. Early diagnosis and treatment are imperative to preventing progression.
Can CRPS spread to other areas of the body?
In some cases, CRPS can spread beyond the initial affected area, either to the opposite limb or other regions. This does not happen in every patient but is a recognized possibility.
Can CRPS be misdiagnosed?
Yes, CRPS is frequently misdiagnosed because its symptoms can resemble those of other conditions, such as arthritis, nerve injuries, or circulation problems. A thorough evaluation by a specialist is important for an accurate diagnosis.
How long does it take to diagnose CRPS?
Diagnosis timelines vary. Some patients are diagnosed within weeks, while others may go months or longer without a clear answer. Early recognition of symptoms can help speed up diagnosis and improve outcomes.
Can CRPS be cured?
There is currently no definitive cure for CRPS, but many treatments can help manage symptoms and improve quality of life. Early intervention increases the chances of significant improvement or remission.
What should I avoid if I have CRPS?
It's generally best to avoid prolonged immobility, extreme temperatures, and activities that worsen pain. Ignoring symptoms or delaying treatment can also lead to progression, underscoring the importance of early care.
Does stress make CRPS worse?
Yes, stress can intensify CRPS symptoms. Emotional stress may heighten pain sensitivity and trigger flare-ups, making stress management techniques an important part of treatment.
How can I manage CRPS pain at home?
At-home management may include gentle movement or physical therapy exercises, stress reduction techniques, heat or cold therapy (as tolerated), and following your prescribed treatment plan. Consistency is essential to maintaining mobility and reducing flare-ups.
When should I see a doctor for CRPS?
You should see a doctor as soon as you notice persistent, severe pain following an injury, especially if it is out of proportion to the original injury or accompanied by swelling, color changes, or sensitivity. Early evaluation can make a significant difference.
How many ketamine treatments are needed for CRPS?
The number of ketamine treatments varies by patient. Many protocols involve a series of infusions over several days, followed by maintenance treatments as needed based on symptom relief and response.
How quickly does ketamine work for CRPS pain?
Some patients experience relief within hours to days after their first infusion, while others may notice gradual improvement over multiple sessions. Response times vary depending on the severity of the condition.
How long do the effects of ketamine therapy last?
Relief from ketamine therapy can last from weeks to months. Some patients require periodic booster treatments to maintain results, depending on how their symptoms respond over time.
Can CRPS go away on its own?
Some patients experience improvement or even remission, especially when doctors diagnose and treat CRPS early. However, many people need active treatment to control symptoms and prevent long-term complications. Early intervention helps reduce nerve sensitization, preserve mobility, and improve overall function.
Is CRPS considered a lifelong condition?
CRPS can become chronic, but it does not always remain severe or progressive. With a comprehensive pain management plan, many patients gain meaningful relief and return to daily activities. Ongoing follow-up allows your provider to adjust treatments as your symptoms change.
How do you decide which treatment is right for me?
Our specialists evaluate your symptoms, medical history, imaging results, and prior treatments. Because CRPS affects everyone differently, we tailor care to your specific needs. Some patients respond well to nerve blocks or therapy, while others benefit from advanced options such as spinal cord stimulation or ketamine infusions. We focus on improving function, not just reducing pain scores.
What makes ketamine helpful for CRPS?
Ketamine works differently from traditional pain medications. It targets NMDA receptors involved in central sensitization, which plays a key role in CRPS. In carefully monitored medical settings, ketamine infusions may reduce severe nerve pain and improve tolerance to movement and therapy. Your provider at Interventional Pain Specialists of Wisconsin, SC, determines whether this option is appropriate for your condition and overall health.
When should I see a pain specialist for CRPS?
You should seek evaluation if pain feels disproportionate to your injury, spreads, or does not improve with standard care. Early assessment by our pain management specialists can help prevent progression and protect long-term mobility. If CRPS is affecting your quality of life, our team offers comprehensive, individualized care to help you move forward with confidence.
