A bruise may appear days after a larger bruise due to the body's process of healing and the movement of blood within the tissues. When a larger bruise occurs, blood can seep into surrounding areas, leading to delayed bruising as the body's inflammatory response continues. Additionally, factors such as activity or pressure on the leg can cause microtrauma in different areas, resulting in a new bruise forming some time after the initial injury.
