Complex Regional Pain Syndrome – Autoimmune or Functional Neurologic Syndrome

One of the great challenges of medicine is to effectively manage pain, a symptom that accompanies many illnesses or injuries. Patients who voice physical symptoms like pain for which no disease cause can be found are extraordinarily common across all medical disciplines. Pain is a symptom that exists to alert us to an injury or malady, such as an infection or a tumor. Pain is meant to be a protective mechanism, but once it has served that purpose, its root cause, physical or psychological, must be effectively treated for the benefit of the patient.
