Pain Management to Improve Quality of Life

Management of chronic pain requires a comprehensive approach to both diagnosis and treatment. Our physicians treat chronic pain with a wide variety of techniques, including image-guided epidural, transforaminal, and facet spinal injections as well as with targeted joint injections.  Our pain management team is led by Dr. Donald Macron and Dr. Jonathan Raanan, who are Board-certified Physiatrists and Assistant Professors in the departments of Neurological Surgery and Physical Medicine and Rehabilitation at Stony Brook University Hospital.  Dr. Macron emphasizes the use of non-pharmacological and non-surgical procedures to optimize function and activity.  He is fellowship trained in sports and spine rehabilitation medicine, and has published in textbooks on spine injury and rehabilitation, as well as in several journals, including the Annals of Thoracic Surgery and Pain Physician.   Dr. Raanan concentrates on the diagnosis and treatment of disorders of the spine and has a special interest in physical therapy and non-surgical procedures to control chronic pain.  He also serves as the Director of Outpatient Services for the Department of Neurosurgery at Stony Brook University Hospital.
