I have a very small bump on the right side of my nose. It is usually flesh colored and not very noticeable but every few months it starts to get red. I try to pop it but nothing but lots of blood ever comes out. It feels like a piece of glass is stuck in it. I squeeze to let it really bleed, it's red and sore for a few days then goes back to flesh colored. A few months later the process starts over. Any ideas what it could be?
