Causalgia is best defined as what kind of sensation?

Causalgia, also known as complex regional pain syndrome type II, is characterized by an intense burning pain that occurs following an injury to a sensory nerve. This type of pain is often described as severe and debilitating, and it can persist long after the initial injury has healed. The term itself derives from Greek roots, where "caus- " refers to burning and “algia” refers to pain, which aptly describes the sensation experienced by individuals with this condition. The distinguishing feature of causalgia is its association with nerve injury, setting it apart from other types of pain, such as dull aches, sharp pains, or tingling sensations, which are common in different medical conditions but do not encompass the same mechanisms or severity as causalgia.
