Piercings !!

Soo i got my ear pierced at piercing pagoda on december for my 19th birthday ! I really took care of it , i cleaned it every day with the ear care solution they gave me . Everything was ok with it till last month that i noticed like a little ball on it . So i went there and literally the woman said " girl i'm not a doctor" ... so i went through internet and they say a way to get rid of it is putting  some saline solution two times a day  ( i'm already doing that) , but i'm kinda scared this can get bigger or something . And im not brave enough to take it off and put another one . If anyone knows something🙏🏻🙏🏻 

I know the ball is really small but still concerns me
