Researchers from the University of Adelaide, in Australia, report that long-term opioid use increases patients' sensitivity to certain types of pain.

According to an article on Medscape news, "David Clark, MD, from the Palo Alto VA Health Care System, in California, has also studied opioid-induced hyperalgesia. According to Dr. Clark, '[An] important finding in this study was that not only addicts have this type of sensitization. Chronic-pain patients have it as well, so this problem goes beyond the boundaries of what is unique to drug abusers.'"
