What Are Rashes and Inflammatory Skin Conditions?

A rash is any visible change in the skin. It may include redness, bumps, dryness, or irritation. Inflammatory skin conditions happen when the skin reacts to triggers such as irritants, allergens, or internal factors. Some rashes are short-lived. Others may come and go. While many are mild, understanding causes of skin inflammation helps you respond calmly and safely.
Quick self-check:
  • Is your rash itchy or painful?
  • Did it appear after contact with something new?
  • Is it spreading or staying in one place?
  • Do you feel unwell or have a fever?

  • Heat rash: Small bumps caused by sweat buildup
