Lumps in Forehead After Fat Transfer to Temples? How Did They Get There? Will It Go Away?

I'm a 29 female & received fat transfer almost 2 months ago into my temples. Most of the fat is already gone, but now there is a hard, noticeable lump in my forehead, a few inches above the outer portion of my eyebrow. I tried firm pressure to flatten it out, but it only looked more swollen somehow. Did pressing on it make it worse? Will it go away on its own? What do I do? I'm also confused over why there would be a lump in my forehead when I had no fat transferred there.
