Dolor, which is derived from Latin, specifically refers to pain in the context of acute inflammation. When inflammation occurs, it is characterized by several cardinal signs, and pain is one of the key features. This pain arises due to various factors, including the release of inflammatory mediators like prostaglandins and bradykinin, which sensitize nerve endings, and from the pressure exerted by swelling in the area.

Understanding this term is crucial in recognizing how inflammation manifests clinically. While swelling, heat, and redness are also important aspects of the inflammatory response, they are represented by other terms: edema for swelling, calor for heat, and rubor for redness. Each of these components contributes to the overall experience of inflammation and plays a role in the body's response to injury or infection. However, in the context of your question, dolor distinctly denotes the sensation of pain, making it the correct answer.
