Erythema
Erythema is a medical term that refers to redness of the skin caused by increased blood flow to the area. This condition can occur due to various factors, including inflammation, infection, or allergic reactions. Common examples of erythema include sunburn and rashes associated with conditions like eczema or psoriasis.
Erythema can be localized, affecting a specific area, or generalized, covering larger parts of the body. It is often accompanied by other symptoms such as swelling, warmth, or pain. Treatment typically focuses on addressing the underlying cause, which may involve medications or lifestyle changes.
