What is Pain?

"Chronic pain has a distinct pathology, causing changes throughout the nervous system that often worsen over time. It has significant psychological and cognitive correlates and can constitute a serious, separate disease entity."

- Relieving Pain in America, Report by US Institute of Medicine, 2011

 

The International Association for the Study of Pain (IASP) defines pain as "an unpleasant sensory and emotional experience associated with actual or potential tissue damage."

 

All pain is an individual human experience that is entirely subjective and can only be truly appreciated by the person experiencing the pain.

 

Acute pain is pain that lasts for a short time and occurs following surgery or trauma or other condition. It acts as a warning to the body to seek help. Effective timely treatment is essential to prevent transition to chronic pain.[i]

 

Chronic pain is pain that lasts beyond the time expected for healing healing following surgery or trauma or other condition. It can also exist without a clear reason at all.

 

Some forms of chronic pain, for example pain associated with severe osteoarthritis, may be treated with therapy which may include medication or surgery; however other types of chronic pain, such as neuropathic pain or migraine, may be far more difficult to diagnose and treat.

 

A large body of basic research indicates that chronic pain is associated with neuroplastic changes in the nervous system at peripheral, spinal cord and brain levels. Thus chronic pain is shown to have a distinct pathology that often worsens over time, and constitutes a serious separate disease entity.[ii]

 

Left untreated, chronic pain can have a devastating impact on all aspects of sufferers' lives. About 65 percent of people with chronic pain report interference with daily activities including sleep, sex, work, exercise and routine self-care, which can have a negative effect on personal relationships, social interactions and lifestyle.

 

Cancer pain is one of the most feared aspects of cancer. It can occur in patients with both early stage and advanced disease, and in cancer survivors as a severe and debilitating side-effect of treatment.

Chronic Pain in Children and Adolescents

 
Although the greatest incidence of chronic pain occurs in the 50-54 age bracket for women and the 55-59 age bracket for men, it also occurs in children and adolescents.

Children and adolescents can experience chronic pain through a wide range of medical conditions such as juvenile rheumatoid arthritis, scoliosis, cancer, migraine and chronic abdominal pain, or as a result of spinal cord injuries.

Untreated chronic pain in children is likely to manifest in low school attendance, poorer grades, and cessation of sporting or other activities.

For some, the eventual result is social isolation and depression, and these children tend to become adults who are not able to achieve their potential.

Therefore, parents and carers should seek medical advice if children or adolescents under their care are complaining of pain on a regular basis.
