The specialty of Pain Medicine is concerned with the prevention, evaluation, diagnosis, treatment, and rehabilitation of painful disorders. Such disorders may have pain and associated symptoms arising from a discrete cause, such as postoperative pain or pain associated with a malignancy, or may be syndromes in which pain constitutes the primary problem, such as neuropathic pains or headaches. The diagnosis of painful syndromes relies on interpretation of historical data; review of previous laboratory, imaging, and electro-diagnostic studies; behavioral, social, occupational and a vocational assessment; interview and examination by the pain specialist; and may require specialized diagnostic procedures, including central and peripheral neural blockade or monitored drug infusions. The special needs of the pediatric and geriatric populations are considered when formulating a comprehensive treatment plan for these patients. The pain physician serves as a consultant to other physicians but is often the principal treating physician and may provide care at various levels, such as direct treatment, prescribing medication, prescribing rehabilitative services, performing pain relieving procedures, counseling of patients and families, direction of a multidisciplinary team, coordination of care with other healthcare providers and consultative services to public and private agencies pursuant to optimal healthcare delivery to the patient suffering from a painful disorder. The pain physician may work in a variety of settings and is competent to treat the entire range of painful disorders encountered in delivery of quality health care.
