You’re going about your day when you notice them — tiny red dots on your arm. They don’t itch. They don’t hurt. They’re easy to ignore.
But what if I told you that these small red spots could be more than just a harmless skin quirk — and might actually be a warning sign from your body ?
While some red spots are completely benign, others can signal underlying health issues — from liver problems to blood disorders , vitamin deficiencies , or even autoimmune conditions .
Let’s explore the most common causes of small red spots on the skin — and when you should stop ignoring them .
What Are These Small Red Spots?
The tiny red spots you might see on your arms, legs, or torso are often called:
- Petechiae – Pinpoint red, purple, or brown spots caused by broken capillaries
- Cherry angiomas – Bright red, dome-shaped bumps caused by clustered blood vessels
- Purpura – Larger purple or red patches from bleeding under the skin
