Is it ok to put a curved piecing in my lip while it heals?

It's probably not the best idea but you could do it. just be sure to clean it often that way it heals faster. I would wait till it healed a little more because if it's in the beginning stages of healing, then it will hurt more since it's more sensitive. If I were you I'd do it. I get bored of piercings quick and change them often. just suck it up and deal with the pain. ice it or something after. it will probably be red and swollen for an hour or so.
