[Filer] The day I got forehead filler

I only got 2cc of forehead filler on the side of the indentation, but they didn't do any molding?? But it will happen naturally on its own. But right after I did it, it was very lumpy. So I asked again and they said it was because of the swelling... Is this right..? And it's been 3 hours since I did it, and my forehead is so numb and it hurts like a bruise. Will this not regenerate once I peel it off? I really regret it so much. I thought it was simple, but it hurts more than I thought..
