How and when to treat fat necrosis/fibrosis - 3 months post-op TT. (photos)

I have developed fat necrosis right under my belly button. I have been getting aggressive massages with ultrasound and wearing my faja with ab board faithfully and the area is not budging at all. Everyone says give it time but its frustrating. At what point can I assume that the area is not going anywhere and seek some type of corrective procedure?
