Incision area getting darker: The first picture is 3 days post op. Is it a rupture? Or just bruising? (Photos)

Hello and thank you for your question.Based on the photos it appears to be bruising but be sure to bring up any concerns with your surgeon.Good luck!

If you have a postoperative concern, you should bring the issue up to your surgeon.  They have a better ability to evaluate your issues and make sure there are no acute problems than asking online sites like this one.
