What is the status of those biopolymers in my body by these MRI's? In what phase do you think that I am? (photos)

I believe I was victim of biopolymer injections in my buttocks. I was told it was hialuronic acid, but now I know that's impossible. It was 6 years ago, and it has not been reabsorbed. I do not have any change of color in my gluteus or hardness. However, sometimes i feel pain in my legs back and gluteus . I'm going to see a surgeon at the end of this month, but I feel that's a long time for me to have an answer. The MRIs are without contrast.
