For example, people with chronic pain know the pain will recur, and they may become fearful and anxious as they anticipate the pain's return. When people understand that worsening pain may not indicate damage to their body, they may have less anxiety (for example, about deteriorating physically or losing function) and thus have less pain.
Rarely, people have persistent pain with evidence of psychologic disturbances and without evidence of a disorder that could account for the pain or its severity. This pain may be described as psychogenic. However, psychophysiologic pain is a more accurate term because the pain results from interaction of physical and psychologic factors. For example, fear and anxiety can reduce the production of substances that reduce the sensitivity of nerve cells to pain. This change in sensitivity to pain partly accounts for pain that persists after its cause resolves and for pain that feels more severe than expected. Psychogenic pain is far less common than nociceptive pain Nociceptive Pain Nociceptive pain is caused by an injury to body tissues. (See also Overview of Pain.) Most pain is nociceptive pain.

The fact that pain is worsened by psychologic factors does not mean that it is not real. Most people who report pain are really experiencing it, even if a physical cause cannot be identified. Doctors always investigate whether a physical disorder is contributing to chronic pain but often do not find an adequate explanation for the pain.
Drugs to relieve pain
Nondrug treatments such as biofeedback
Often psychologic counseling
Pain that is heavily influenced by psychologic factors requires treatment, often by a team that includes a psychologist or psychiatrist. Treatment for this type of pain varies from person to person, and doctors try to match the treatment with the person’s needs.
For most people who have chronic psychogenic pain, the goals of treatment are to improve comfort and physical and psychologic function.
Doctors may make specific recommendations for gradually increasing physical and social activities.
