Blood blister

Overview

A blood blister can occur when the skin is rubbed, bruised or pinched. The unbroken skin that covers the blister may provide a natural barrier to bacteria and decrease the risk of infection.

Symptoms

A blood blister looks like a blood-filled bubble covered by skin

Treatments

A blister usually heals on its own. One that doesn't heal or becomes infected needs medical attention.
