Rash

A rash is a skin eruption with various appearances, causes, and associated symptoms like itching and pain. It can be triggered by allergies, infections, or underlying medical conditions and can be acute or chronic.

A rash is a visible skin eruption that can manifest in various forms, including macules (flat, discolored spots), papules (small, raised bumps), vesicles (small, fluid-filled blisters), wheals (itchy, raised welts), or scaling. Rashes can be localized to a specific area or widespread across the body. The appearance of a rash can vary significantly depending on the underlying cause, which can include allergic reactions (e.g., to medications, foods, or environmental allergens), infections (e.g., viral exanthems, bacterial skin infections), autoimmune diseases (e.g., lupus, psoriasis), irritant or contact dermatitis (e.g., from harsh chemicals or poison ivy), drug reactions, or certain underlying medical conditions. Symptoms associated with a rash may include itching (pruritus), burning, pain, swelling, and tenderness. The rash can be acute (sudden onset and short duration) or chronic (long-lasting or recurring).
