I had rhinoplasty about 5 months ago. I had a closed rhinoplasty and originally only wanted to reshape the tip of my nose to make it look more feminine, as it was too wide for my liking. I ended up deciding to also make the bridge a bit more narrow. Since removing the bandages, I noticed a small bump and it seems to have only gotten bigger. It feels hard like bone. I've read that it could be a callus. If that's the case, what is the procedure done to get it removed?
