Pain exists as a symptom of many different conditions. Problems as simple as a cut finger and as complex as Diabetes Mellitus can result in pain. The most important distinction between types of pain is between pain that is acute and pain that is chronic. Often we attempt to define chronicity by the length of time that a condition or symptom has been present, but more accurately, chronic conditions are marked by pathological changes that occur in the chronic state of an illness and are not necessarily present in an acute state. These changes in a condition foretell a permanence of symptoms, where acute conditions are often thought to be reversible. Still this definition is inadequate because it is inevitable in certain acute conditions that the initial symptoms will pass into a state of chronicity. Probably the best way to define a painful condition as chronic is to look at both the length of time it is present and the pathological changes that have occurred that distinguish it from the acute state. By keeping this in mind, the most timely intervention in a painful condition to reduce the overall pain is the most likely to result in a reversible or well-controlled outcome.

To understand the Disease of Chronic Pain, we have to evaluate and treat the patient in the separate arenas of the physical injury, the psychological effect of that injury and the social adjustments that have occurred as a result of the injury. Although it is tempting to look at chronic pain as a purely physical event, this is rarely, if ever, the case. People who suffer with chronic pain experience a sequence of events that alters their lives and may manifest as a spectrum from the simple to most complex set of circumstances. Patients with chronic pain should be seen as going through a series of cascades, the biological, the psychological and the social. Successful treatment should take into account all three cascades and attempt to intervene in all three spheres. A typical pattern in each cascade would be as follows:

Biological:

Psychological:

Social:

Hence, the disease of chronic pain must be understood as a process that not only occurs over time and with pathological changes that distinguish the chronic condition from the acute condition, but also as a disease that has an effect upon the entirety of a persons life. If all treatment is directed at the biological manifestation of pain, there is little likelihood that the patient's condition will have a satisfactory resolution. A treatment plan for successfully treating chronic intractable pain should involve interventions at the biological, psychological and social level. The goal of this treatment should not be the complete end of chronic pain, but instead a reasonable level of pain control and improved function. An effective treatment plan would involve the following:

Biological:

Psychological:

Social:

These treatment approaches sometimes unfold in different order and the variations that occur with individual practitioners can represent the art of pain medicine, but the general ideal of touching upon all three life spheres is extremely important if good outcome to treatment is to be achieved.
