Chronic pain is reoccurring or continuous pain that persists for longer than two weeks. It is usually caused by a disease or the body’s abnormal reaction to injury or stimulus, tends to be less intense than acute pain, but can be just as debilitating. Anesthesiologists specializing in pain management have the expertise and training to be able to diagnose and treat complex pain cases. Chronic pain management techniques vary greatly from patient to patient. Some techniques used include prescription medicines, nerve blocks, continuous epidurals, spinal blocks, nerve stimulators and narcotic infusions.
