A skin rash is a noticeable change in the texture or color of the skin, often resulting in redness, swelling, or irritation. Rashes can occur due to various factors, including allergies, infections, or underlying medical conditions. Common types of rashes include eczema, psoriasis, and contact dermatitis. Treatment for skin rashes depends on the cause and may involve topical creams, antihistamines, or other medications. It's important to identify the trigger to prevent future occurrences. If a rash persists or worsens, consulting a healthcare professional is recommended for proper diagnosis and management.
