Bruising on nose tip four days post-op from second tip plasty revision. Should I be concerned?

I am just post-op of my third tip plasty. The only thing I noticed after my first two surgeries is that cold would turn my nose very red. Immediately after my third surgery four days ago, much of the tip turned a deep red purple. Should I be concerned? It may have lightened a little since the surgery day but not much. I have very deep purple bruises under my eyes and a lot of swelling. My surgeon's office tells me its par for the course to have bruising on the tip. Is that accurate?
