Anyone ever had a fat necrosis lump the size of a golf ball go away on its own? It’s been months and mines still here

I had surgery in July and I have a lump the size of a golf ball near the top of my breast and it still hasn’t gone away. It doesn’t hurt but I can feel it. It’s been months and I’m losing hope that it will go away on its own.

Wondering if anyone has had theirs go away on its own even after months
