Which of the following is a symptom of angina?

Angina is typically characterized by cramping chest pain or discomfort that occurs due to reduced blood flow to the heart muscle. This pain often feels like pressure, squeezing, or a feeling of fullness in the chest and can sometimes radiate to other areas, such as the arms, neck, jaw, or back. This symptom is a critical indicator of the heart not receiving enough oxygen, often triggered by physical exertion or stress.

In contrast, severe headaches, high fever, and severe swelling in the legs are not associated with angina. Severe headaches may suggest issues such as migraines or other types of headaches, high fever could indicate an infection or inflammatory response, and swelling in the legs may point to conditions like heart failure, kidney issues, or venous insufficiency, but none of these symptoms directly relate to the angina itself. Understanding angina's specific symptoms can aid in recognizing and responding to potential cardiac issues effectively.
