After Rhinoplasty, is It Normal to Have Internal Swelling Where the Stitches Were Placed?

I had rhinoplasty 3 weeks ago. The tip is very swollen, and I have noticed is that inside the nose, there is a lot of swelling especially in the internal part of the tip, something like hard bumps inside the nose. Initially, I thought it was a crust, and I tried to remove it until I realized I was bleeding. Is this swelling normal? How long does it take to come down? I assume once it comes down the swelling in the tip will diminish. Is that right? Thank you!!!
