Swelling follows, often due to the accumulation of fluid and immune cells in the tissue, creating pressure and discomfort, which is the pain response. Pus formation typically indicates an accumulation of dead white blood cells, bacteria, and tissue debris in response to the infection, which can be a critical sign of a bacterial infection.
