Nose stitches are hurting me two weeks after rhinoplasty. Is that normal?

I didn't feel any pain through the last two weeks until now. I also returned to work after 10 days and for the last 5 days I have been working so hard (i work in retail). My doctor said work won't affect my nose anymore but can hard work cause more pain? Im thinking to rest for a couple of days. My doctor did not prescribe anything for my nose stitches. He said I'm recovering very well.
