Permanent Prolene sutures causing pain. I feel them 6 years later. How to remedy this issue and prevent further issues? (Photo)

Tummy Tuck Aug 2012. In 2015 I started having issues with a painful suture and it was removed. This is in the pictures I provided. Now I have another painful suture by my belly button. If anything presses this area I get a sharp pain. I can feel the bumps where other sutures are but they are not painful, at least not yet. What are my options to fix this and also prevent future scars on my abdomen? Is this worth having my abdominal skin lifted and all remaining sutures removed?
