I got my piercing almost a month ago and everything was going great. Yeah it hurts once in a while but I heard it was normal. But today I woke up and it looks as if my ear swallowed my piercing! I'm literally freaking out. Should I take it off? Or should I soak it in water with salt and see if it gets better?

No don't take it out, start bathing it in salt water and keep it clean.
