When acute pain, regardless of its cause, is not treated promptly and properly, it becomes chronic pain and is no longer the symptom of a disease, but rather, it is the disease. The World Health Organization (WHO) considers and classifies pain as a disease.
Chronic pain is the pain that continues to exist for a long period of time (more than 3 months). It can remain stable or fluctuate, affecting many aspects of an individual's everyday life and emotions.
Unfortunately, the care for individuals with chronic pain is insufficient. Painful conditions that are not adequately treated with the usual therapeutic methods require a more holistic and multifactor approach.
Nowadays, the effort to interpret in biological terms the syndrome called central sensitization has led to new therapeutic approaches. If the initial acute pain from injury or tissue damage is not treated effectively, then nociceptive signals are transmitted continuously to the brain. As a result, changes are formed in the central nervous system (plasticity), that makes it increasingly sensitive to pain stimulation. Consequently, a small irritation is enough to stimulate a large part of the brain. In this state even natural stimuli can be received as painful.
The goal of every treatment is to re-program the functions of the nervous system at lower levels of sensitivity (pain threshold), remapping pain pathways at the lower level to make the nervous system less vulnerable and, as a result, more resistant to pain.
