What term is used for pain caused by tissue injury and the release of chemical mediators?

The term that describes pain caused by tissue injury and the subsequent release of chemical mediators is inflammatory pain. This type of pain arises as part of the body's response to injury or infection, where damaged tissues and immune cells release substances that lead to the sensation of pain. These chemical mediators enhance pain sensitivity and contribute to the inflammatory response, prompting both local and systemic effects aimed at healing.

Chronic pain, unlike inflammatory pain, persists over an extended period, often outlasting the initial injury or inflammation and may not be directly associated with ongoing tissue damage. Neuropathic pain is a distinct category caused by damage to the nervous system itself, such as nerve injury or disease, rather than by the inflammatory response to tissue injury. Acute pain, while it can be related to tissue damage, is typically a short-term experience that signals immediate harm and is not specifically linked with the inflammatory process in the way inflammatory pain is. Thus, inflammatory pain appropriately encompasses the concept of pain arising directly from tissue injury and the accompanying release of chemical mediators.
