My married daughter's nose has been sore for about a week with some minor blood when she blows it. We just thought it was some cracking due to the extreme low temps and low humidity. She went to the doc in a box because it hurt so much and they said it was cold sores/canker sores in the nose. She had no idea of how to treat it and recommended my daughter go to a real doc on Monday.
Has anyone ever heard of this and if so, what to do?
She's always been prone to cold sores in the mouth, as opposed to those on the lips.
