I am 2 weeks post op and accidentally pulled a stitch out of my nose. Did I cause damage? (Photo)

I am scared that I have caused damage by pulling a stitch out of my nose 2 weeks post op. I was gently picking on the inside of my left nostril where there was lots of crusty dried blood when I noticed a small black stitch had come out with the dried blood. There was no pain but my nose is tingling a lot now. I had septoplasty, turbinectomy , grafts, and rhinosplasty. Thank you very much in advance for any answers!
