Bone sticking out of cartilage inside nose? (photo)

I have a little bit of white bone sticking out of my cartilage inside my nose. It's not painful and it's not affecting my breathing (because it is very small) but I've had it for a couple of years and it's starting to annoy me now. I've been to my GP and he seems clueless about it and without his approval I am unable to see an ear nose and throat doctor to determine the cause.
