I get these paper cut like fissures in exact same spot every November/December. Must be due to heating coming on and drying me out. Edge of nose hurts a lot and I apply almond or argan oil and keep in moist which helps. Your info was great to read for now I know I better seek help if it doesn’t go away. In past, I did have anal fissure and doctor ignored when I looked for help, and so it became an anal fistula which resulted in two surgeries.
