CRPS Syndrome: Symptoms, Diagnosis, and Treatment

Complex Regional Pain Syndrome (CRPS), also known as Reflex Sympathetic Dystrophy (RSD), is a chronic and often debilitating condition characterized by severe and persistent pain, swelling, and changes in skin temperature and color. This blog post provides an overview of CRPS, including its symptoms, diagnosis, and treatment options.

What is CRPS Syndrome

CRPS is a neurological disorder that can occur after an injury, surgery, or trauma to a limb. The pain associated with CRPS is often disproportionate to the initial injury and can be very intense, making it difficult to carry out daily activities.

CRPS Symptoms

CRPS symptoms can vary from person to person, but generally include:

  • Severe and constant pain in the affected limb
  • Swelling and stiffness in the affected area
  • Changes in skin color and temperature (the affected area may be warm or cool to the touch)
  • Skin sensitivity or hypersensitivity
  • Muscle weakness and atrophy
  • Difficulty moving the affected limb

There are two types of CRPS

  • CRPS type 1: This type of CRPS occurs after an injury or trauma to a limb that did not directly damage the nerves. It used to be called RSD.
  • CRPS type 2: This type of CRPS occurs after a specific nerve injury.

Causes of CRPS

The exact cause of CRPS is not yet fully understood. However, it is believed that CRPS occurs as a result of dysfunction in the nervous system. It may be triggered by an injury, surgery, or trauma to a limb.

Risk Factors for CRPS

Certain factors may increase a person’s risk of developing CRPS, including:

  • Having a history of anxiety or depression
  • Being a woman
  • Having a history of migraines
  • Having a previous injury or surgery to the affected limb
  • Having a family history of CRPS

CRPS Diagnosis: How Is It Diagnosed?

Diagnosing CRPS can be challenging since there is no specific test or diagnostic criteria. Instead, doctors rely on a combination of physical exams, medical history, and imaging tests. Your doctor will likely ask about your symptoms and conduct a thorough physical exam to assess your skin temperature, color, and texture, as well as your muscle strength, flexibility, and sensitivity.

Your doctor may also order some imaging tests, such as an X-ray, MRI, or bone scan, to rule out other conditions that can cause similar symptoms. In some cases, your doctor may recommend nerve conduction studies or electromyography (EMG) to evaluate nerve function and activity.

CRPS Treatment Options

There are several treatment options available for CRPS, including:

  • Medications: Over-the-counter pain relievers, such as acetaminophen and ibuprofen, may help relieve mild to moderate pain. In more severe cases, your doctor may prescribe stronger pain medications, such as opioids or anticonvulsants.
  • Physical therapy: Physical therapy can help improve your range of motion, strength, and flexibility.
  • Nerve blocks: Nerve blocks involve injecting a local anesthetic into the affected nerve to help relieve pain.
  • Sympathetic nerve blocks: Sympathetic nerve blocks involve injecting an anesthetic into the nerves that control the blood flow to the affected area.
  • Spinal cord stimulation: Spinal cord stimulation involves implanting a small device under the skin that delivers electrical impulses to the nerves in the affected area, helping to reduce pain.
  • Surgery: Surgical interventions may include sympathectomy, a procedure that involves cutting or destroying the sympathetic nerves responsible for transmitting pain signals, or implantation of a spinal cord stimulator, a device that sends electrical impulses to the spinal cord to help control pain.”

Diagnosis of CRPS: What to Expect

If you experience any of the symptoms mentioned above, it is important to seek medical attention as soon as possible. Your doctor will perform a physical exam and ask about your medical history to determine if you have CRPS. There is no specific test to diagnose CRPS, so your doctor will rely on your symptoms and medical history to make a diagnosis. Other tests may be ordered to rule out other conditions that can cause similar symptoms.

Treatment of CRPS: What You Need to Know

There is no cure for CRPS, but early intervention can help manage the symptoms and prevent the condition from getting worse. The goal of treatment is to control pain, restore function, and improve quality of life. Treatment options may include a combination of medications, physical therapy, and occupational therapy. In severe cases, surgery may be necessary.

Medications for CRPS

Several different types of medications may be used to treat CRPS, including:

  • Pain relievers such as acetaminophen, ibuprofen, and aspirin
  • Opioids such as morphine, oxycodone, and fentanyl
  • Antidepressants such as amitriptyline, duloxetine, and venlafaxine
  • Anticonvulsants such as gabapentin and pregabalin
  • Corticosteroids such as prednisone and methylprednisolone
  • Topical medications such as lidocaine patches and capsaicin cream

Physical Therapy for CRPS

Physical therapy can help improve mobility and reduce pain and stiffness associated with CRPS. Your physical therapist may use a variety of techniques, including exercise, stretching, massage, and electrical stimulation.

Occupational Therapy for CRPS

Occupational therapy can help you learn new ways to perform daily activities, such as dressing and bathing, that may be difficult due to CRPS. Your occupational therapist may also recommend assistive devices to help make daily activities easier.

Surgical Treatment for CRPS

In rare cases, surgery may be necessary to relieve pain and improve function. Surgical options may include spinal cord stimulation, sympathetic nerve blocks, or sympathectomy.

Self-Care for CRPS

Self-care can play an important role in managing CRPS symptoms. Some self-care tips to try include:

Practicing stress-reduction techniques, such as meditation and deep breathing

  • Staying active with low-impact exercises such as swimming, walking, or biking
  • Applying heat or cold therapy to affected areas
  • Getting enough rest and practicing good sleep hygiene
  • Eating a healthy, balanced diet
  • Coping with CRPS
  • Living with CRPS can be challenging, both physically and emotionally. It’s important to seek support from friends, family, and healthcare professionals. Joining a support group or speaking with a mental health professional can also be helpful.

Prevention of CRPS

There is no guaranteed way to prevent CRPS, but early intervention and treatment can help prevent the condition from getting worse. If you experience any symptoms of CRPS, seek medical attention right away.

Understanding the Diagnosis Process

When a patient presents with symptoms of CRPS, the doctor will typically conduct a physical examination and review the patient’s medical history. A diagnosis of CRPS is usually made based on the patient’s symptoms and medical history, as well as the results of any diagnostic tests that may be ordered.

Diagnostic Tests for CRPS

Diagnostic tests that may be used to diagnose CRPS include bone scans, X-rays, and magnetic resonance imaging (MRI) scans. These tests can help to identify any abnormalities in the bones, joints, or soft tissues that may be contributing to the patient’s symptoms.

Treatment Options for CRPS

There is no known cure for CRPS, but there are a variety of treatment options that can help to manage the symptoms and improve the patient’s quality of life. Treatment options may include physical therapy, medication, nerve blocks, and spinal cord stimulation.

Physical Therapy for CRPS

Physical therapy can be an effective treatment option for patients with CRPS. The goal of physical therapy is to improve the patient’s range of motion, strength, and flexibility, and to reduce pain and swelling. Physical therapy may include exercises, stretching, massage, and other techniques.

Medication for CRPS

Medication can be used to manage the pain and other symptoms of CRPS. Commonly used medications include nonsteroidal anti-inflammatory drugs (NSAIDs), opioids, and anticonvulsants. The choice of medication will depend on the patient’s symptoms and medical history, as well as other factors.

Nerve Blocks for CRPS

Nerve blocks are a type of injection that can be used to block the transmission of pain signals from the nerves to the brain. This can be an effective treatment option for patients with CRPS who are experiencing severe pain. Nerve blocks can be temporary or permanent, depending on the patient’s needs.

Spinal Cord Stimulation for CRPS

Spinal cord stimulation is a type of therapy that involves the implantation of a small device under the skin of the back. The device delivers electrical pulses to the spinal cord, which can help to reduce pain and other symptoms of CRPS. Spinal cord stimulation may be recommended for patients who have not responded to other forms of treatment.

The Importance of Early Treatment

Early treatment is essential for patients with CRPS. The sooner treatment is initiated, the better the chances of managing the symptoms and preventing the condition from progressing. Patients who are experiencing symptoms of CRPS should seek medical attention as soon as possible to ensure that they receive timely and appropriate treatment.


CRPS is a complex and often debilitating condition that can have a significant impact on a patient’s quality of life.
