Scar tissue - how to deal with it

My little update: three weeks almost post surgery. Well it has been a long saga. I saw the surgeon on Monday and two weeks post surgery, the stitches were still there so he told me to put toothpaste on them and give them a good rub. Well, I have to say in my case this did not work and I ended up having a lot of pain in my stitches. I wish he had taken the time to just remove the stitches. I saw a nurse in my local health centre who removed them for me and it was immediate relief. The pain I was having in one of my stitches went immediately. But now I am left with quite a bit of scar tissue and it is quite bumpy so my lip doesn't feel like it has gone back to normal as I can feel this bump rubbing against my upper lip. Nothing visible but I am scared another evil mucocele will show up. The other thing is a tiny bit of pus comes out sometimes from another bit where there used to be a stitch - strangely not the one that was painful, It doesn't hurt or anything. I keep rinsing with salt water to help prevent infection. I think what has happened here is that the stiches were left for too long and now I am paying the price for it. They should have fallen out naturally but didn't :(
What is the best way to deal with scar tissue? Anyone else worried about the way it felt in your lip which reminded you of your old mucocele?
God Bless this forum, don't know where else I could go to talk about this.
