For the past few nights I put a glob neosporin on the end of my nose and put three band aids loosely over it. It works on hang nails and infections so
I gave it a go. Today it's looks almost perfectly healed. Guess the end of my nose was infected. What I was doing right before this happened? Pumping gas. Last time I put my hands on a dirty gas pump handle and touch my nose without washing my hands.
Oh I was worried alright :)
No idea, but suggest you think about what was going on before the red started, maybe you simply bumped into something - "dontworry" if it goes away on its own, otherwise see your doctor.
