How can a complication from Cellfina be fixed?

Cellfina April 2016...1 1/2 later. 3 mo check up with hard lump on right side of butt check (no treatment). 3 mo later kenalog shot. 3 mo later dr reversed shot with saline. Hurt badly/bruised created indention. 3 mo later hard lump still there & dr injected juvaderm. That was 2 weeks ago. The lump is still there and the shot did nothing. I wasn't told what this was caused from and I really want answers and a solution. The skin above the lump feels looser & it wasn't there before Cellfina.
