This constant or intermittent pain has often outlived its purpose, as it does not help the body to prevent injury. It is often more difficult to treat than acute pain. Expert physician care is generally necessary to treat any pain that has become chronic. When opioids are used for prolonged periods drug tolerance, chemical dependency and even psychological addiction may occur. While drug tolerance and chemical dependency are common among opioid users, psychological addiction is rare.
