Monroe piercing question?

i have had my monroe pierced for about a month and a half now and up until this point it has been healing nicely. a week ago i went into the tattoo shop i got it done at and got it changed from the standard flat back silver stud to a plastic/jewel thing, a day later i took it out because the post was too short. i have been keeping up on my oral care (i have braces too so cleaning my mouth is must with or without the monroe) and taking care of the outside with h2ocean as well. recently i noticed a little tenderness right at the hole and on the inside a little bit. i pulled my lip up to see if anything was abnormal on the inside because everything is fine on the outside and noticed a little flap of skin growing by the hole. it is only attached by the hole and is a normal lip color. i moved it around and it didn't hurt, just felt awkward. the flap isn't trying to grow over the back of the stud as far as i can tell because it is only attached by the hole in one very small place. i have always had a little indention from the flat part of the stud but it has never done this. does anyone know what this is called or has had this happen to them? will the piercing be okay if i keep taking care of it and taking an anti inflammatory to keep swelling down and the stud from tugging at my lip? also, i cant easily go back because my parents were pretty against another facial piercing and already told me the second it got infected or something was weird i would have to take it out. this is not an option for me so i cant tell them to take me in. again- the stud is fine.. very high grade metal, the outside looks great (no peeling no redness no discharge), but the inside has a little flap of skin growing directly to the right of the hole (not over the back just to the right). thanks for your answers.
