Protruding bone/cartilage on the nose bridge 3 years post-op rhinoplasty - advice? (photos)

I had rhinoplasty performed 3 years ago. Recently it seems like there's a protruding piece of cartilage/bone on my nose bridge. Ever since surgery my nose bridge was very ridged and uneven but it wasn't visible. Now there's also some discolouration (very white skin) where the bump is protruding. I am worried it might get worse since I currently have to wear tight-fitting ffp2 masks every day, which seems to be the cause of it. What can I do?The skin seems very thin around that area.
