A blood blister is a specific blister that is formed when blood vessels beneath the skin are ruptured, but the surface of the skin isnât actually broken. As a result, the body basically bleeds underneath the skin, and blood pools up beneath the skin, along with lymph and other fluids.
In some cases, a blood blister may be formed by some sort of steady wear, such as a pair of shoes that donât fit properly being worn on a long hike. They may also be formed as a result of frostbite, in which the blood vessels beneath the skin burst from the expansion of the liquid in them, but the skin is never broken.
