Red dots on the skin are common and can have various causes. Here’s a simplified list of potential causes: Petechiae and Purpura: These “tiny red dots appear due to damaged blood vessels” and can result from stress or medications.
They may indicate platelet disorders. Cherry Angiomas: Small, raised, bright red bumps that are “generally harmless” and more common with age. Heat Rash: Occurs when sweat gets trapped in ducts, leading to red, itchy dots.
