Red dots on the skin are a common occurrence and can stem from various causes. Here’s a simplified overview:
- Petechiae and Purpura: Tiny red dots caused by damaged blood vessels, often due to stress, medications, or platelet disorders.
- Cherry Angiomas: Small, raised, bright red spots that are generally harmless and more prevalent with age.
- Heat Rash: Red, itchy dots resulting from trapped sweat in ducts.
- Allergic Reactions: Triggered by food, substances, or insect bites, causing redness and itching.
- Folliculitis: Red, pus-filled bumps caused by inflamed hair follicles, often due to bacterial or fungal infections.
- Cellulitis: A bacterial skin infection requiring medical treatment with antibiotics.
- Impetigo: Contagious bacterial infection marked by red sores that ooze fluid and form crusts.
- Vasculitis: Blood vessel inflammation linked to autoimmune disorders.
- Hemangiomas: Harmless birthmarks from abnormal blood vessel growth, sometimes needing medical attention.
If red dots are accompanied by symptoms like fever or pain, consult a healthcare provider—better safe than sorry!
