Is it normal for chin filler to still be dissolving after 28 mths? Tingly feeling with inflamed bumps and dark patches.

I had 1ml Teosyal in my chin in July 2020. From 4 months after to Nov 2021 my chin would get tingly and inflamed and bumpy, then the bumps would fade and leave a dark area I now realize was filler disintegrating. One bump lasted a year before going away. I was told the filler would last 1 yr and assumed it was all gone ... but in the last few days I've gotten the same inflamed feeling and bumpiness followed by dark patches! Is it normal for filler to still dissolve after 28 mths?
