What Are Red Dots on the Skin?
Red dots on the skin, also known as petechiae or cherry angiomas, are small, flat, or raised marks that can vary in size and appearance. They can appear individually or in clusters and may be accompanied by other symptoms such as itching, pain, or changes in skin texture.
Common Causes:
- Petechiae:
Petechiae are tiny red or purple dots that occur when small blood vessels called capillaries break and bleed under the skin. They often appear in clusters and can be caused by a variety of factors, including:
Trauma: Excessive pressure or injury to the skin, such as vigorous scratching or rubbing, can cause petechiae to develop.
Straining: Prolonged straining during activities like vomiting, coughing, or childbirth can increase pressure in the blood vessels, leading to petechiae.
Medical Conditions: Certain medical conditions, such as infections, autoimmune disorders, or deficiencies in blood clotting factors, can also cause petechiae to form.
