3 months post-op: Is sutures not dissolving and increased pain normal? (Photos)

May 5 abdominalplasty completed. Complained to surgeon four weeks post op due to a loop aprimimately 4 inches of suture hanging out of umbilicus exposed, then slowly other areas started opening with sutures popping through. After an ER visit and 9 week check up surgeon then said sutures not dissolving and needed revision to remove scar tissue. Revision on 7/25/17, now I have sutures hanging out of umbilicus, appears like fishing line, and have mass amount of nerve pain around umbilicus.
