Thick scar tissue which has created a small bulge along my jawline. Will this go away?

Hi doctors. I had a small area of my jaw lipo 9 months ago. In the first 2 month, my smile was crooked, but I have now regain all function. However, underneath my skin, I have developed a weird sensation that feels like thick scar tissue which has created a small bulge along my jawline. Could my nerves be stretched and injured? Will this go away? Thank you
