Tiny red spots on your skin — especially your arms, legs, or torso — may seem harmless, but sometimes they’re your body’s warning sign. While many, like cherry angiomas, are “generally not dangerous,” others such as petechiae or purpura can signal deeper issues.
**What Are They?**
* *Petechiae* are pinpoint red or purple dots from broken capillaries.
* *Cherry angiomas* are bright red, harmless bumps linked to aging.
* *Purpura* are larger patches from bleeding under the skin.
**Possible Causes:**
1. **Blood Disorders:** Petechiae can be linked to low platelets, infections, or autoimmune issues. “If petechiae appear suddenly, spread quickly, or are accompanied by fever,” seek medical help.
2. **Liver Disease:** Red spider-like spots and red palms may point to liver issues. Watch for other signs like jaundice or swelling.
3. **Vitamin Deficiencies:** Lack of vitamin C or K weakens vessels, causing red spots.
4. **Physical Strain:** Heavy lifting, vomiting, or tight clothing can cause harmless, temporary spots.
5. **Autoimmune Conditions:** Lupus or vasculitis can lead to persistent rashes or petechiae.
**When to Act:**
Seek help if spots don’t fade when pressed, spread fast, or are paired with fatigue, bruising, or joint pain. A simple blood test may reveal the cause. As the article warns, “the smallest red flag… can lead to the biggest health discovery.”
