It can be alarming to find small red dots suddenly appearing on your skin. These spots, often no bigger than a pinhead, may seem harmless at first—but they could be your body’s way of signaling that something is off. Known as petechiae, these red or purple spots appear when tiny blood vessels under the skin break and bleed. They don’t fade when you press on them and can occur anywhere on the body. While sometimes benign, they may indicate a more serious underlying condition.
One common cause of petechiae is physical strain. For example, heavy lifting, intense coughing, or vomiting can lead to pressure that bursts capillaries, especially on the face or chest. However, if red dots appear without any clear cause or are spreading, it could suggest an infection, such as strep throat or even more serious illnesses like meningitis or sepsis. In such cases, other symptoms like fever, fatigue, or bruising might also occur, and medical attention is crucial.
Another potential cause is a reaction to certain medications, such as blood thinners, antibiotics, or chemotherapy drugs. Petechiae can also be a symptom of blood clotting disorders or vitamin deficiencies, particularly vitamin C (scurvy) or vitamin K. Autoimmune diseases, like lupus or vasculitis, can also manifest with red spots. Paying attention to other symptoms and timing can help your doctor determine the cause more quickly.
