Blood Blisters: Causes, Symptoms & Treatment - What You Need To Know
Ever noticed a dark, ominous bubble forming on your skin after a minor mishap? It's highly probable that you're looking at a blood blister, a common yet often misunderstood skin ailment. While typically harmless, understanding what they are, how they form, and how to differentiate them from other similar-looking conditions can save you unnecessary worry and ensure proper care.
Blood blisters, medically speaking, are a type of blister that contains blood. Unlike regular blisters filled with clear fluid, blood blisters arise when blood vessels beneath the skin's surface rupture, causing blood to pool within the blister. This usually occurs due to trauma, friction, or pressure.
