Retained suture: This may be a retained suture, now causing a delayed "foreign body" reaction. The site should be examined to make sure there are no signs of infection as well.

The "Thread": May be non-absorbable suture material. If it is open, then this material is irritating the area and will need to be removed. See your surgeon.
