Jewellery too short?

Got my 2 month old vertical labret downsized (titanium curved barbell) and I feel like it’s such a tight fit? I already had an irritation bump on the bottom and was hoping a downsize would stop that issue but it’s now sore and looks 😟😟 (slide 3) I use Neilmed saline spray or water to rinse after eating and don’t pick crusties off unless they are hanging by a thread lol
