Bruising is indeed a common sign of internal bleeding. When blood vessels are damaged, blood can leak into surrounding tissues, resulting in discoloration of the skin in the form of bruises. This can occur without any external trauma being visible. Bruising can vary in color from blue or purple to yellow as it heals, providing a visible indication of the underlying bleeding.

Other signs of internal bleeding might include abdominal pain, swelling, or tenderness, which are often associated with severe internal injuries. While loss of consciousness, severe headaches, and excessive sweating can indicate a variety of medical issues, they are not definitive signs of internal bleeding on their own. Bruising stands out as a direct visual cue that suggests there has been blood accumulation, making it a key indicator in assessing potential internal injuries.
