What can I do about persistent nodule from HyalDew All cheek filler?

I had cheek fillers for the first time last November and have been wondering what to do to restore my natural face. the right cheek filler had a decent sized nodule immediately after treatment that persised beyond the first two weeks. We dissolved, but its still there. At this point I have dissolved 5 times. I know the filler is likely gone because my overall structure is back, but this knot is still there and especially apparent when smiling. My smile and muscles look disfigured.
