How to heal nostril piercing bump inside nose?

I pierced my nostril a little over a month ago. It was healing well until 2 weeks ago I accidentally snagged. It ended up getting an irritation pump around the stud, externally. I tried everything that was advised, including sea salt soaks, and it didn’t go down, until I used a silicone gel scar sheet and it completely went down and back to normal overnight. I only realised today that there’s a bump inside the nostril now, it’s around the bar. This bump looks different from the one externally though. This one is almost a perfect rounded circle around the bar, while the external bump was not, it was much more uneven and had a larger bump on one side. Is this internal bump normal? If not, what can I do to let it go down?
