What is complex regional pain syndrome?

CRPS is a specific form of chronic pain affecting your arm or leg. There are two different kinds of complex regional pain syndrome, type 1 and type 2.

Type 1, or reflex sympathetic dystrophy (RSD), occurs when you have an injury without any confirmed nerve damage. Approximately 90% of CRPS cases are type 1. Alternately, type 2 develops when there’s proof of nerve damage.

CRPS isn’t very common. It usually develops between the ages of 40-70 years and is more likely to occur in women.

What causes CRPS?

The exact cause of CRPS isn’t known, though it’s likely an autoimmune condition that leads to inflammation. It often develops after you go through a significant health episode, such as a stroke, heart attack, surgery, or injuries like broken bones.

Some people who develop complex regional pain syndrome could also have pre-existing irregularities in their nervous system that make them more sensitive to injury. CRPS is also seen more often in people with a family history of the condition.

What are the symptoms of CRPS?

CRPS can cause a wide range of symptoms that affect a finger or toe or your entire arm or leg. Common signs of complex regional pain syndrome include:

  • Persistent burning or throbbing
  • Hypersensitivity to touch or cold
  • Swelling
  • Changes in skin temperature, color, or texture
  • Changes in your nail or hair growth
  • Joint damage, swelling, or stiffness
  • Muscle spasms or tremors
  • Muscle loss or weakness
  • Reduced mobility

When you have CRPS, it’s common to have symptoms that change over time. They can also move to other areas of your body.

How is CRPS diagnosed and treated?

Dr. Amirdelfan has advanced training diagnosing and treating complex pain disorders like CRPS. In most cases, he diagnoses CRPS through a comprehensive physical examination, reviewing your medical history, and looking for signs of the condition, like swollen joints and skin changes.

In addition to a physical exam, Dr. Amirdelfan might recommend a variety of tests to rule out underlying issues and confirm a diagnosis.

Based on your diagnosis and symptoms, Dr. Amirdelfan might recommend a variety of therapies to manage your condition, such as:

  • Physical therapy
  • Nerve blocks
  • Epidural injections
  • Intrathecal infusion

Dr. Amirdelfan may also recommend spinal cord stimulation, or SCS, to disrupt nerve pain signals going to your brain.
