4 days after nose fillers, is it possible to still have swelling?

Got my fillers 4 days ago. Still very mildly achy when touched but not much, feels like a pimple on my nose sort of feeling. But I notice a bump on one side as well as top of the bridge, since the day of procedure and now has improved but it’s still there. Is this normal and part of swelling? Should I massage it? Is 4 days too early to tell?
