Hi! I had dpfl 6months ago and developed hematoma(evacuated). At 5months I still had tethered firm areas infront of ear from cheek to jaw.Doc saw this contracture so he injected 5 fu. Now 1 months later I have alot relief.But there's 1 spot behind jaw angle under ear.This spot isn't as tender as before injection but didn't get as much improvement(lump contour wise)as the rest.I know there's a nylon suture around there. Can this be a suture issue or this area has more scar tissue? How to fix it?
