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 skin conditions like eczema and psoriasis. They can appear anywhere on the body and may be itchy, painful, or uncomfortable. Treatment for skin rashes depends on the underlying cause. Over-the-counter creams, antihistamines, or prescription medications may be used to relieve symptoms. It's important to consult a healthcare professional if a rash persists, worsens, or is accompanied by other symptoms, such as fever or difficulty breathing.
