10 years old septum piercing - columella drop and swelling over the years with no pain. What can I do? and what is it? (Photo)

I had my Septum pierced 10 years ago. is it possible it made my columella drop?no pain. the columella is hard, if i push the nose up there is a bump which is visible from outside.you can see the shape of metal that goes through it plus,the area between the columella-cartilage,is like a big hard marble inside the skin,(seems one side is more swollen) Is it treatable now?what is the swelling?can i reduce it?once i take off the piercing and it closes,is it going to change a little? Thank you!
