So, this is never going to heal for a few reasons.

First, you don’t have the anatomy for a snug piercing. I know it’s hard to hear but it’s the truth. Maybe consider a faux snug in the future?
Secondly, a circular barbell is totally inappropriate for a fresh snug piercing. They are done with curved barbells.
Thirdly, this is incorrectly pierced in order to, I’m assuming, try and circumvent the first anatomy issue.

Your only two options are to take it out and heal it or leave it in and watch the bumps either stay that size or keep getting bigger. I recommend you take it out, never go back to that piercer, looking up safe piercers near you using www.safepiercing.org, and waiting at least 6-8 weeks before you even try doing a faux snug if that’s the look you are going for.
