Is it possible to break down fibrosis that has developed under my skin, 19 months after facelift?

I had asked my surgeon many times about pulling at the sides of my face, that seemed to develop many months after my surgery. He said that he didn't know what it was. Eventually he discharged me. Obviously I was unhappy about this but was getting nowhere. It was only by chance that the nurse prescriber, told me it is probably fibrosis. She used to work for a plastic surgeon and I respect her knowledge. Is there anything, realistically, that can be done to soften this?
