Dear Cpn,
You could try bentonite clay. You mix the powder with water to reconstitute the clay. Apply it thickly (a few millimeters) and cover with a waterproof bandage. Use overnight. It could take time (even doing this nightly for a couple of weeks) but it may draw it to the surface. It would be an inexpensive and simple thing to try!

That's a puzzle, isn't it? If it's closed and healed and "good to go" and the stitches aren't changing color, I'd shower, make up epsom salt paste, apply a blob to the area over the stitches and put a waterproof bandage on it for a day and see if it shifts them.
Epsom salt paste is just epsom salt with enough water to make a paste. It can draw out just about any foreign thing, right through the skin.
Some dissolvable stitches are blue so I'm not sure what you mean by that. If they're dissolvable and you can see any of them, you'll notice them changing colors if they're dissolvable.
