Pain Management Center

Through the combined expertise of a multidisciplinary team of pain specialists, the Columbia Pain Management Center offers patients a full range of services including evaluation, diagnosis, medication management, anesthesia-based procedures, and cutting-edge, image-guided interventions. With six interventional pain management physicians and two psychologists, we integrate psychological evaluation and behavioral modalities in our comprehensive pain management approach. To facilitate the treatment of chronic pain, we also offer holistic modalities (including acupuncture), health coaching, and nutritional strategies for metabolic and obesity management.



Chronic pain, such as chronic pelvic, abdominal, or postoperative pain

Musculoskeletal conditions, including all types of arthritis pre- and post-joint replacement, chronic pain secondary to herniated discs or spinal stenosis at cervical, thoracic, and lumbosacral regions

Autoimmune disease–related pain

Vascular pain secondary to insufficient blood supply to extremities

Cancer or cancer treatment related pain

Neurological pain, including facial pain (e.g., trigeminal neuralgia), fibromyalgia, headache disorders, peripheral neuropathy, carpal tunnel syndrome, complex regional pain syndrome (reflex sympathetic dystrophy syndrome), and pain after shingles, stroke, amputation

Although a diagnosis or condition may be focused on a particular region or body part, we know that pain often is not limited to a single body system. We care for our patients with a comprehensive, “whole body” approach.
