Bleeding under the skin happens when tiny blood vessels break, resulting in discoloration. This can manifest in various ways, depending on the amount and location of bleeding.
Types of Bleeding Under the Skin
- Petechiae: These are tiny, pinpoint-sized red dots caused by broken capillaries.
- Purpura: This involves larger, flat areas of discoloration.
- Ecchymosis: This refers to a large bruise, a common example being a black eye.

- Autoimmune Disorders: Conditions like lupus or rheumatoid arthritis can weaken blood vessels, leading to bleeding. [Source: Mount Sinai]
- Viral Infections: Some viral illnesses can affect blood clotting, increasing the risk of bleeding. [Source: Mount Sinai]
- Thrombocytopenia: This condition, characterized by low platelet count, impairs blood clotting. [Source: Mount Sinai]
