Spitting Stitches & Fat Necrosis?

I had TT In March 2014 and have continued to have rejected internal sutures make their way out externally either through puncturing my belly button, along my TT incision line and the most recent rejected suture is making its way out thru my pubic area where the drainage tube was place post op. Fat Necrosis is this 6mm hard mass above my belly button and below my breast bone, it's painful & tender. Do I have any other options regarding removal of mass & Internal sutures other than surgery?
