What is chronic pain
Chronic pain is the sensation of discomfort that lasts more than six months and unresponsive to conventional therapies for their control, such as surgery, medication, rest, physical therapy or other means. When it reaches this stage we can consider that the pain has ceased to be a sign to become a disease.
It should be mentioned that some authors report that chronic pain is one that lasts more than three months or beyond the normal period of recovery.
Chronic pain is an entity that according to estimates in the United States affects half of the population present in some parts of the body. In Mexico it is believed that the figure may be the same. Chronic pain can last for years and causes severe damage to the quality of life of the person and although many diseases cause pain for the organ damage that affect chronic pain syndrome has no identifiable physical cause and this is stated with such when the patient is subjected to tests of all types and apparently there is a cause that justifies it.
