What is Complex Regional Pain Syndrome?

Complex regional pain syndrome, also known as CRPS, is a chronic pain condition most often affecting one limb, usually after an injury, surgery, stroke, or heart attack.

Causes and Symptoms

  • The exact cause is not well understood, but CRPS typically occurs after a trauma, surgery, or nervous system damage.
  • Symptoms can include prolonged severe pain, swelling, changes in skin color, temperature, and texture, and impaired motor function in the affected area.

Diagnosis and Treatment

  • Diagnosis involves a physical examination and patient history, and may also include imaging tests, nerve conduction studies, or sympathetic nervous system tests.
  • Conservative treatments include physical therapy, psychotherapy, and medications to manage pain and inflammation.
  • Interventional treatments can involve nerve blocks, spinal cord stimulation, peripheral nerve stimulation, or intrathecal drug pumps.

Goal of Treatment

  • The primary goal is to reduce pain, improve function, and maintain quality of life by managing symptoms.
