How long will malar edema after filler last?

34 year old woman with terrible first time filler experience. I had filler injected in tear trough area 10 months ago. I developed Tyndall effect under one of the eyes due to poor injection technique. The filler was dissolved (multiple attempts) but I have had swelling under that eye ever since. I have tried laser treatments, Xela Rederm, and nothing has worked. Recently I was told from a Dr. it was likely molar edam and nothing could be done. Am I stuck with this forever?
