What are the primary symptoms of inflammation?

The primary symptoms of inflammation are characterized by the classic signs: redness, heat, swelling, and pain. These symptoms arise due to the body's immune response to injury or infection.

Redness occurs as a result of increased blood flow to the affected area, which also contributes to the sensation of heat. Swelling is caused by the accumulation of fluid and immune cells in the tissue, which often leads to the presence of pain as a result of pressure on the surrounding nerves or tissue damage. This combination of symptoms is fundamental to the inflammatory response as the body attempts to isolate and eliminate harmful agents and initiate the healing process.

Understanding these symptoms is crucial in identifying inflammatory conditions and differentiating them from other medical issues, allowing for appropriate management and treatment.
