What causes red and swollen nose

The cause of a red and swollen nose can vary depending on a number of factors. Common reasons for a red and swollen nose include skin conditions, allergies, irritation, infection, and injury. Some common skin conditions that can cause a red and swollen nose are rosacea, dermatitis, and perioral dermatitis. Allergies, such as allergic rhinitis or contact dermatitis, can also lead to a red and swollen nose due to the body's immune response to certain substances. Irritation from external factors such as harsh soaps, detergents, or chemicals can also cause a red and swollen nose. Infection with bacteria or viruses can also be a factor, especially if the skin is already irritated or broken. Injury to the nose, such as a bump or bruise, can also result in redness and swelling. If you have a red and swollen nose that does not seem to be going away or is accompanied by other symptoms such as pain, discharge, or difficulty breathing, it is important to consult a doctor for proper diagnosis and treatment. A doctor can assess your symptoms, determine the underlying cause, and provide appropriate treatment recommendations.
