Bullfinch vein and uneven skin in the temple from Bellafill. Will it subside? It’s been a month with no change.

I had Bellafill in my temples 3 weeks ago, for volume. One side is perfect. The other has a large lump and the PA is reporting it’s normal and will even out. He said it’s not the bellafill, but swollen blood vessels. He told me to put hot compress on and massage but still no change. Will this lump be permanent? Will I have to get surgery to remove it? Are there other things I could do to reduce swelling?
