Acute pain has a physiological protective role in preventing tissue damage. However, pain can become chronic due to a multitude of pathophysiological states, such as: trauma, inflammation, neural injury, viral infection, cancer, autoimmune diseases and vascular and metabolic disorders. These pathological states can trigger alterations of the pain pathways that can lead to hypersensitivity, and in such circumstances, pain loses its protective role and instead, becomes persistent and debilitating affecting seriously to the quality of life of patients.

Chronic pain is one of the most important health problems worldwide. It has been estimated that 10% of adults are diagnosed with chronic pain each year. However, despite the high prevalence of chronic pain, its management is still no fully satisfactory probably due to the variety of chronic pain conditions with different etiologies (neuropathic, visceral and musculoskeletal pain), and because their pathophysiological mechanisms are only partially known. Therefore, there is a huge need for new effective therapies for the control and/or prevention of the different types of chronic pain.

Chronic pain is associated with plastic changes in pain circuits of the peripheral and central nervous system, including changes in the expression of ion channels, neurotransmitters and receptors. In addition, there is growing consensus on non-neuronal mechanisms that can amplify or resolve chronic pain, and cells traditionally thought to act just as coordinators of the inflammatory response (such as immune and glial cells) are now accepted as real modulators of pain signaling. In this regard, animal models of persistent pain, such as models of neuropathic and visceral pain and models of arthritis, are helping to elucidate our understanding of the pathogenesis of chronic pain and make it possible to test experimental treatments.

The purpose of this Research Topic is to collect original research studies as well as review and perspective articles that provide recent advances and future directions in the pathophysiology and treatment of chronic pain. We welcome the submission of preclinical or clinical manuscripts, especially those describing emerging targets for the treatment of chronic pain. However, manuscripts describing new methods for the study of pain or opinion articles exposing a particular point of view about any aspect of chronic pain are also welcome.
