Chronic pain is different from acute pain in that it continues even after the initial injury or disease has healed. With chronic back pain, pain signals can remain active in the nervous system for weeks, months and even years. For this reason, chronic back pain often disrupts patients’ daily lives and causes significant emotional distress. If you suffer from chronic back pain, don’t hesitate to contact Dr. Susan A. Baker, a board-certified doctor of both internal medicine and rheumatology. A recipient of both the “Patient’s Choice Award” and “Most Compassionate Doctor” award, Dr. Baker is known for offering an exceptionally high level of empathy and patient care in Los Angeles.
