What Those Red Dots on Your Skin Might Be Telling You
Have you noticed small red spots on your skin and wondered what they could mean? While many red spots are harmless, some can be signs of a health problem that shouldn’t be ignored. In this guide, you’ll learn about the possible causes of red spots, when to see a doctor, and what steps you can take to treat them.
Understanding Red Spots on Your Skin
Red spots, also known as betechiae, angiomas, or rashes, can appear anywhere on your body. They can vary in appearance: they can be flat or raised, itchy or painless, and temporary or permanent. Often, the cause determines their characteristics and whether they need treatment.

Cause: Bleeding under the skin, often associated with infections, trauma, or blood disorders.
When to worry: If petechiae appear suddenly or are numerous, they may indicate a serious condition, such as a clotting disorder.
