The skin in my nose has been splitting off and on again since July. July is when I had the worst case, as it started with these cuts in my nose and developed into a much bigger issue. My entire nose entrance was swollen, making breathing a hard feat. I eventually went to a doctor who diagnosed me with impetigo. It went away, and so did the cuts, but over the months, these cuts will come back and then leave over and over. Is it just allergies or is something wrong?
