Driven by a relentless pursuit to alleviate pain, Dr. Massey's journey began in his home state of Texas, where he graduated from Texas Tech University. His passion for anesthesiology led him to California for residency, during which he encountered the debilitating effects of chronic pain, particularly Complex Regional Pain Syndrome (CRPS). Recognizing the profound impact CRPS has on individuals' lives, Dr. Massey dedicated himself to finding solutions. He furthered his expertise through a fellowship in pain management at Rush University, where he had the privilege of learning from two professors who were instrumental in creating the Budapest Criteria, the gold standard for diagnosing CRPS.

Today, Dr. Massey stands as a beacon of hope for those grappling with CRPS. His commitment to providing compassionate and comprehensive care is evident in his approach. He believes in fostering open communication, ensuring patients feel heard and understood throughout their journey to pain relief.

What is Complex Regional Pain Syndrome (CRPS)?

Complex Regional Pain Syndrome (CRPS) formerly known as causalgia, is a chronic pain condition characterized by an overactive nervous system response. It typically affects one or more limbs, often following an injury, surgery, or even seemingly minor events like a flu shot. Dr. Massey explains, "Essentially, it's an overreaction of the nerves due to damage, leading to inflammation and persistent pain signals."

What Causes CRPS?

The precise cause of CRPS remains elusive. However, it's widely believed to involve a combination of factors, including:

  • Injury or Surgery: The most common triggers for CRPS are injuries or surgeries, particularly those involving the limbs.
  • Nervous System Dysfunction: An abnormal response of the nervous system, including the sympathetic nervous system, plays a crucial role in CRPS.
  • Immune Response: An inflammatory response, possibly even an autoimmune reaction, may contribute to the development and progression of CRPS.
  • Other Risk Factors: Certain factors can increase susceptibility to CRPS, such as poor circulation, diabetes, prior nerve damage, autoimmune disorders, and even psychological distress.

Diagnosis of Exclusion: CRPS is often diagnosed when other potential causes of the patient's pain have been ruled out.

CRPS is classified into two types:

CRPS Type 1

CRPS Type 1 (formerly RSD): This type is characterized by an overactivity of the nervous system, often leading to symptoms like swelling, changes in skin color and temperature, and tremors. The key distinction is that there is no identifiable nerve injury in CRPS Type 1. It often occurs after trauma or crush injuries where multiple minor nerves are damaged, making it difficult to pinpoint the exact source of the pain.

Reflex sympathetic dystrophy (RSD) is an older term that was once used to describe CRPS Type 1. While the terminology has evolved, the underlying condition remains the same.

CRPS Type 2

CRPS Type 2 (formerly causalgia): This type also involves an overactive nervous system response, but it is distinguished by the presence of a clear nerve injury. The pain and other symptoms can often be traced back to the specific damaged nerve.

CRPS Diagnosis

CRPS diagnosis often involves a process of elimination, ruling out other potential causes of the patient's pain. While there's no single definitive test, a skilled pain specialist like Dr. Massey can reach an accurate diagnosis through a thorough evaluation of medical history, physical examination, and potentially additional tests like bone scans or nerve conduction studies. The Budapest Criteria, a set of clinical diagnostic guidelines, further aids in confirming CRPS. Early diagnosis is crucial for effective treatment and better outcomes, emphasizing the importance of seeking help promptly if you suspect you may have CRPS.

Complex Regional Pain Syndrome Stages

CRPS often progresses through three distinct stages, each with its own typical timeframe and set of symptoms:

  • Stage 1 (Acute): This early stage, usually lasting up to 3 months, is characterized by intense burning pain and noticeable changes in the skin, including swelling (edema), redness (erythema), and sometimes inflammation (dermatitis). While bone involvement is not typically seen in this stage, the pain can be severe and disproportionate to the initial injury.
  • Stage 2 (Dystrophic): Occurring between 3 and 6 months after onset, this stage is marked by worsening edema, skin thickening, and the beginning of muscle wasting (atrophy). Pain often persists or even intensifies during this phase.
  • Stage 3 (Atrophic): This is the chronic stage of CRPS, typically starting after 6-12 months. It's characterized by decreased range of motion, joint contractures, further skin atrophy, and significant demineralization of the bone, as seen on X-rays. Pain intensity can vary during this stage, but the functional limitations become increasingly pronounced.

Recognizing these stages and their typical time frames is critical for guiding appropriate treatment and minimizing the long-term impact of CRPS. Early diagnosis and intervention are key to managing symptoms and improving quality of life.

Complex Regional Pain Syndrome (CRPS) Symptoms

CRPS manifests in a variety of symptoms that can significantly impact a person's daily life. These symptoms can vary in intensity and may change over time. They include:

  • Severe pain: This is the hallmark of CRPS. The pain is often described as burning, throbbing, or shooting, and it can be disproportionate to the initial injury.
  • Sensory changes: The affected area may become hypersensitive to touch, temperature, or even light pressure.
  • Motor changes: Stiffness, decreased range of motion, muscle weakness, or tremors can occur.
  • Autonomic changes: These affect the body's automatic functions and can lead to changes in skin color, temperature, sweating, and hair or nail growth.
  • Trophic changes: The skin and tissues in the affected area may become thin, shiny, or even develop ulcers.

Symptoms of CRPS Spreading

In some cases, CRPS can spread beyond the initial site of injury or affected limb. This phenomenon, referred to as "spreading CRPS," can involve the opposite limb or even distant areas of the body. While the exact mechanisms behind CRPS spreading are not fully understood, it is believed to involve a complex interplay of the nervous system and immune system. Early recognition of spreading symptoms is crucial for timely intervention and management.

If you notice new pain, swelling, or other CRPS symptoms in areas beyond the original site, it is essential to inform your healthcare provider promptly. They can assess the situation and adjust your treatment plan accordingly to address the spreading CRPS and help manage your pain effectively.

CRPS Treatment and Therapies

At PSA, we believe in a personalized approach to CRPS treatment. Dr. Massey emphasizes, "We start with the most conservative therapies and gradually escalate if needed. The goal is to find the most effective treatment plan for each individual patient."

  • Physical Therapy and Occupational Therapy: These therapies can help improve range of motion, strength, and function, as well as reduce sensitivity in the affected area. Desensitization therapy, which involves gradually exposing the affected area to different textures and temperatures, can be particularly helpful.
  • Sympathetic Nerve Blocks: These injections can temporarily block nerve signals and provide pain relief, especially in CRPS Type 1.
  • Spinal Cord Stimulation and DRG Stimulation: Nerve stimulators are advanced therapies that involve implanting a device that delivers electrical signals to the spinal cord or dorsal root ganglion, disrupting pain signals and providing relief.
  • Psychological Support: Stress and pain are closely interrelated, and chronic pain can take a toll on mental health. Counseling and other forms of psychological support can help patients cope with the emotional challenges of CRPS.

Who Treats CRPS?

A multidisciplinary team is often involved in the treatment of CRPS. At PSA, you'll have access to a dedicated pain specialist like Dr. Massey, who will create a comprehensive treatment plan tailored to your specific needs.

Complex Regional Pain Syndrome Self-Care

In addition to professional treatment, self-care plays a crucial role in managing CRPS. This can include gentle exercises, stress management techniques, maintaining a healthy lifestyle, and following any recommendations provided by your healthcare team.

Debunking Myths: Is CRPS Real?

Unfortunately, one of the most common misconceptions Dr. Massey encounters is the belief that CRPS isn't a real condition. "Some physicians don't know about CRPS and don't see it as a true pathology," he says. This lack of awareness can lead to delayed diagnosis and treatment, which can significantly impact patient outcomes.

Another misconception is that CRPS always involves a clearly identifiable nerve injury. "While this is true for CRPS Type 2, in CRPS Type 1, the affected nerves may be too small to be easily identified with current technology," Dr. Massey clarifies.

However, advancements in medical imaging and diagnostic techniques offer hope for the future. "We're constantly improving our ability to visualize and understand the nervous system. With increased awareness and research, we'll be able to identify and treat CRPS more effectively," Dr. Massey assures us.

A Message of Hope from Dr. Massey

"While I've seen the devastating impact CRPS can have, I want the world to know that it is treatable," Dr. Massey emphasizes. "The earlier we intervene, the better the chances of achieving complete remission. If you're experiencing persistent pain after an injury or surgery, don't hesitate to seek help from a pain management specialist."

Dr. Massey shares a particularly inspiring success story about a young nurse who developed CRPS after receiving a flu shot. "She was in excruciating pain and couldn't even pick up her children," he recalls. "After undergoing spinal cord stimulation at PSA, she experienced remarkable relief and was finally able to embrace her kids again. It's moments like these that make my work so rewarding."
