Quite a few gals have mentioned that their bodies have rejected a suture or two and as a result, their bodies have "spit" them out.
What Does Spitting out a Suture Mean?

What's the Meaning of a "Spitting Suture"?
Although modern stitch materials are much more body friendly than older materials (such as horse hair, cotton, silk, silver, steel etc), and are much better tolerated sometimes the body reacts with an inflammatory response to a stitch creating fluid around it. The pressure of the fluid then burrs a tunnel along the path of least resistance which is usually the scar overhead. The result? A pimple like eruptin which after draining off reveals the bunny ear like cut ends of a tied stitch. Once the spit, exposed stitch is removed the hole closes rapidly. Some stitches are usually more prone to spitting than others but no stitch is immune to this minor complication.
The phrase "spitting sutures" refers to the concept that either permanent or absorbable sutures that are normally just under the skin poke through the skin and are palpable on the outside. Often these are the knots of sutures commonly first apparent at 2-3 weeks after the original procedure. If absorbable they often just pull out, or can be cut at their ends.
