Mismanaged pain is still a major medical problem. Many pain syndromes have no effective treatment, and many are managed poorly. Basic and applied research on pain treatment is hampered by the unobservable nature of pain sensation and the lack of validated measures of this perception.
The purpose of this protocol is to develop and validate improved subjective measures of pain sensation and use these measures to evaluate pain sensitivity in clinical populations. Normal volunteers rate experimentally-evoked pain sensations before and after double-blind administration of the opioid fentanyl or saline placebo. Patients rate experimentally-evoked pain sensations without any drug administration.

Normal Volunteers, including NIH employees, will serve as subjects.
No subjects with any painful disease or diseases in which altered pain sensitivity is suspected.
No subjects will be included with poor general health, history of significant illness, history of psychotic disorder or recent emotional distress, serious heart, lung, or liver disease, or pregnancy.
Subjects also will be excluded on the basis of history of allergy to any of the medications, history of chronic or recent drug use that may alter pain response, or chronic drug abuse.
