Eyebag on left eye after fat transfer to undereye areas 1 month ago, is it just edema or fat overfilled? Will it go away?(photo)

I have fats transfer to areas below my brows and under my eyes to fill up the hollows about a month ago. However, there is now an eye bag under my left eye. There were bruising and hardness right after the procedure but both conditions were resolved the next day with constant icing. However, what remains is still an eyebag that is unchanged since the second day until 30 days later. The eyebag is soft to touch, it doesn't feel lumpy or hard.
