How Does a Popped Blood Vessel in the Hand Occur?

A blood vessel may pop due to injury, bruising, allergic reaction, blood infection or an autoimmune disorder, according to Healthline. A tiny amount of blood flows from the vessel into the surrounding areas when a blood vessel bursts. The blood usually appears close to the skin’s surface.

Bleeding into the skin typically results from a popped blood vessel, says Healthline. It appears as tiny dots, called petechiae, or bigger, flat patches known as purpura. Minor causes, such as bruising, often cause bleeding under the skin. Other causes include medication intake, chemotherapy, radiation and aging. Infections and diseases that lead to bleeding under the skin include strep throat, leukemia, sepsis and meningitis.

An individual can determine whether there is bleeding into the skin by pressing the skin, states Healthline. If the skin turns pale when pressed and gains its usual color or turns red when let go, the person likely does not have a burst blood vessel. However, bleeding has possibly occurred if the skin does not turn pale when pressed.

Individuals should contact a medical professional if they experience pain, bleeding through the skin, dark color on the affected area or swollen limbs, notes Healthline. Prompt medical care is also necessary if bleeding into the skin occurs persistently or with no known cause.
