Hi. I'm 14 years old and I've had this red rash under my nose for years now, but I've finally decided to do something about it. When it first appeared I went to the doctors and got told it was something to do with fungi and got given a nappy rash cream for under my nose. This did not work. I dont only just get redness rash under my nose it also sometimes has flaky skin thats about to fall off. It also looks like red vains under my nose too if i stretch my skin under my nose by moving my mouth down over my teeth.
