8 months post op - Could I have caused the dark circle around my nose tip by massaging the area?

I had rhinoplasty 8 months ago. After the initial first four weeks of healing, and once it was ok’d by my doctor, I started to gently massage my nose. The bridge and the tip. I did it for a couple of minutes every couple of days and only for two weeks.I noticed a dark circle around the tip of my nose. There’s no indentations, just discoloration that looks like a circle in pictures and in the mirror, both with or without makeup. Did I cause this?
