Common Symptoms

• Itching or burning sensations
• Swelling, blistering, or peeling

Types of Rashes

• Eczema: Chronic red, itchy patches often tied to stress or allergens.
• Contact dermatitis: Redness and blisters after touching irritants or allergens.
• Hives (Urticaria): Raised, itchy welts from allergic reactions or stress.
• Heat rash: Small itchy bumps when sweat ducts are blocked in heat or humidity.
• Viral rashes: For example, chickenpox or measles, usually with fever.

Impact on Daily Life

• Sleep disruption from constant itching.
• Social anxiety when rashes are visible.
• Reduced work productivity due to discomfort.

A clear understanding of rash types lays the groundwork for effective trigger identification.
