Chronic Pain Division


With a reputation as a leading authority on pain management, the Center for Pain Management at Stony Brook University Medical Center has served Long Island since 1982. Our program uses the biopsychosocial model of medicine to treat chronic and acute pain, provide palliative care, and improve the functionality and quality of life of our patients. We work in partnership with area physicians to offer consultations, diagnoses, plans of treatment and multidisciplinary care before returning the patient to his or her primary care doctor.

The Center, located within Stony Brook’s Cancer Center, and adjacent to the hospital, offers state of the art facilities, an in-office procedure suite for interventional pain management procedures such as fluoroscopic and ultrasound-guided nerve blocks, infusion therapies, radio frequency ablation, and access to Stony Brook’s wide range of resources and technology. We perform about 2000 procedures per year in our state-of-the-art fluoroscopy suite. We do Interlaminar and transforaminal epidural steroid injections, facet joint blocks and injections, intercostal nerve blocks, stellate ganglion blocks, and lumbar sympathetic blocks on a daily basis. We are one of the few Pain Centers around the country to utilize ultrasound-guided nerve blocks.

Residency Training


The Center for Pain Management utilizes a multi-disciplinary approach for the treatment of pain. Residents will be exposed to chronic, acute, and subacute pain including cancer, neuropathic, somatic, and visceral pain. Residents will learn to perform an initial assessment of the patient with chronic pain, decide on appropriate diagnostic testing, develop skills in performing diagnostic and therapeutic procedures, and learn the appropriate use of pharmacotherapy. In addition, the resident will develop communication skills that will help develop a professional and therapeutic relationship with chronic pain patients.

There is an in-office fluoroscopy suite for epidural, facet, major joint, peripheral nerve blocks, and sympathetic nerve block procedures. Ultrasound guided injections are also utilized. Residents will also be exposed to traditional spinal cord stimulation, as well as dorsal root ganglion stimulation and other treatment modalities such as Botox and IV infusion therapies.

Trainees will greatly expand their knowledge base, skills, and judgment so that they can recognize and manage complications associated with chronic pain. Residents receive hands on training to give them the skills necessary for their fellowship and future careers.

  • The CA-2 rotation is a one month rotation. [Pain Rotation Primer]
  • The three month elective in the CA-3 year is structured as a "mini-fellowship". Residents on the rotation will participate in journal club presentations and receive several core lectures. [CA-3 Mini-Fellowship]
