Erythema (Redness)

Erythema, or redness of the skin, can be caused by hypersensitivity to certain chemicals or as a result of an immune reaction. It can appear as a raised, red rash on the skin or mucous membranes. Understanding the underlying cause of erythema is important for proper diagnosis and treatment. If you notice unexplained redness in your skin, it's essential to seek medical advice to address any potential underlying conditions.
