Which example classifies as acute pain?

Acute pain is typically defined as a sudden onset of pain that is usually associated with a specific injury or condition, often signaling that something is wrong in the body. This type of pain usually lasts for a short period and resolves with recovery from the underlying issue.

Kidney stones exemplify acute pain because the occurrence of these stones often leads to intense, sharp pain, typically in the back or side, that comes on suddenly. This pain is often linked to the movement of the stone within the urinary tract, which results in significant discomfort as the body reacts to this obstruction.

The other examples, such as fibromyalgia, low back pain, and arthritic pain, tend to represent chronic conditions characterized by long-lasting or recurring pain that does not resolve quickly and is not necessarily tied to an acute injury or event. Fibromyalgia involves widespread chronic pain, low back pain can be recurring and may have various underlying causes, and arthritic pain often stems from degenerative changes or inflammation in the joints, developing over time rather than as a sudden episode.
