Sometimes stitches will work themselves to the surface, or the ends of a stitch will pop out. This will sometimes manifest itself as a red spot that peaks in the way a blemish would, and then once it's out it will heal. It can be painful, but it's typically not serious. When the stitch pops out it can look like a piece of soft white rice. If it's not infected, the spot will heal quickly once it's out. Your plastic surgeon can help you with this. If you see your plastic surgeon for a spit stitch, ask him if there is anything you can do for yourself if it happens again, or if he would like you to make a return appointment in the event of a new spot.
