5 days post op rhinoplasty, I think my stitches are infected? (photo)

Although the photos are limited, it appears that your sutures are not infected, and this is part of the healing process.  I would relay your concerns to your surgeon, as he or she will likely want to be apprised of the situation.  Infection in the nose is rare, and usually accompanied by redness, tenderness, drainage, etc.

Hi, thanks for your photos. Based on the pictures you’ve provided it can be difficult to determine if your stitches are infected. I recommend that you follow up with your surgeon in person as soon as possible to address your concerns.

It's impossible to tell from the photos, but you make good points!
I would go in for a visit. Sutures in this location can be removed after 5 days. I do this to minimize scarring.
For now, use Neosporin twice a day. Make an appointment with your doctor for examination and removal.
Hope this helps!
