Most bruises form when small blood vessels (capillaries) near the skins surface are broken by the impact of a blow or injury — often on the arms or legs. When this happens, blood leaks out of the vessels and initially appears as a black-and-blue mark. Eventually your body reabsorbs the blood, and the mark disappears.
Is it normal for random bruises to appear?
Unexplained bruising is very common and heals relatively quickly. However, if a bruise persists, changes in size, or looks unusual, there may be an underlying condition or other factors.
Why is bruises appearing on my body?
A bruise, or contusion, appears on the skin due to trauma. Examples of trauma are a cut or a blow to an area of the body. The injury causes tiny blood vessels called capillaries to burst. Blood gets trapped below the skins surface, which causes a bruise.
