Discoloration or bruising on nose bridge after rhinoplasty?

I had my revision rhinoplasty about 2 and half months ago.I initially had some bruising under the eyes and on my nose bridge. All the bruising are gone within the first two weeks except i can still see a blue/green ish bruise looking spot on the middle of my nose bridge till now. Its not too noticeable but i can see it under certain kind of yellow/bright light. it looks like deep in the skin. I'm wondering if this is discoloration or just bruising? if its discoloration what can i do about it? thank you!
