Bump or swelling possibly reappearing after septo/rhinoplasty?

Hello, I did septo/rhinoplasty about 2 weeks ago. My cast was removed about a week after. The bridge of my nose was smooth and straight, however when I visited my surgeon a week later, he began to touch the nose and the tip to make sure everything was the way it was supposed to be but later that day I noticed a slight bump appear! I'm not sure if it's because he touched/pinched the bridge while checking which caused swelling or if my bump is coming back!!!!
