help getting rid of this irritation bump ASAP

found out i'm getting proposed to sometime very soon and i need this gone ASAP!! this piercing is 11 months old and i’ve had no prior issues at all with healing but just recently i was doing bathroom renovations so i had to wear a mask which im sure is what irritated the piercing to begin with but now im not sure what to do! i'm done with renovations but now stressing over this little irritation bump! my piercer won't be back in town till monday so i have to wait till then to get the top of my flat back stud changed to something that'll be less irritating. for the meantime what could i do??? i’ve been cleaning it with saline solution since yesterday night (the day i first noticed it) and i plan on cleaning it three times a day in hopes that it’ll help
