It might seem harmless at first — small red or purple dots appearing on your skin, especially on your arms or hands. But according to doctors, these marks could be an early sign of something more serious than just an allergy or irritation.

These spots, known as petechiae, occur when tiny blood vessels called capillaries burst under the skin, causing minor bleeding. While they can sometimes appear after coughing, intense exercise, or minor trauma, doctors warn that persistent or spreading petechiae can signal underlying health problems.

👉 Possible causes include:

• Vitamin deficiencies (especially Vitamin C and K)

• Blood clotting disorders

• Infections such as meningitis or endocarditis

• Leukemia or other blood-related diseases

If you notice clusters of red dots that don’t fade when pressed, or if they are accompanied by fatigue, fever, or unexplained bruising, it’s important to see a doctor immediately.

Doctors emphasize that early detection can make a huge difference. What looks like a simple skin issue could, in fact, be your body’s urgent signal that something is wrong.

Bottom line: Don’t ignore small red dots on your skin — they might be telling you more than you think.
