Why is the nose red and swollen

The reason for a red and swollen nose could be due to a variety of factors. It could be a result of an allergic reaction, such as to certain foods or environmental substances, which can cause the skin to become inflamed and red. It could also be a sign of a skin infection, such as a cold or the flu, which can lead to nasal inflammation. Other potential causes include excessive rubbing of the nose, injury to the nose from an accident or fall, and skin conditions like rosacea which often manifests in redness and swelling. If the redness and swelling are accompanied by other symptoms such as pain, discharge, difficulty breathing, or if they persist for a prolonged period of time, it is recommended to seek medical attention. A doctor can examine the condition and determine the cause, and recommend the most appropriate treatment plan.
