What is this swelling? (Photo)

I am 19 years old. Sedentary since graduation, I have fluctuating weight due to eating disorder and I have been fasting & trying to be a healthier weight and only consuming water. But I have noticed swelling in my malar pad area, is it festoons? Thyroid? It seems to be more prominent under my left eye. I have history of blood clots in my family and a mutant gene that thickens blood. I'm quite worried about this swelling, it uncomforts me seeing it. Will this diminish or worsen?
