Suture or scar tissue popping after massage face lift 6 months post op?

Hi! I had dpfl 6 months ago and I still have lump/indent, hardness along the internal smas to deep layer entry site (from cheek to jaw).I did had a hematoma but evacuated.i also have some tether lumps on my neck coz I had a seroma on my neck at thirdweek.Went back to my doctor and he injected 5fu and suggested massage. I used more force last night and heard popping along the tightness. I do feeling softer afterwards tho. Am I doing any harm to the internal sutures or just scar tissue releasing.
