- Impetigo: A contagious skin infection, mostly in kids, that starts with red sores that ooze and form a yellow-brown crust.
- Vasculitis: Inflammation of blood vessels, sometimes related to autoimmune diseases. It can lead to red or purple spots on the skin.
- Hemangiomas: These are benign (non-cancerous) growths made up of blood vessels—usually appear as red or purple birthmarks.
When to see a doctor: If the red dots are painful, spreading, oozing, or come with symptoms like fever or fatigue, it’s best to get them checked out. Better safe than sorry!
