What is this bump on my industrial piercing and how can I treat it? (Photo)

I got my industrial pierced 5 years ago and have had this bump since. I am unsure if this is a keloid or a hypertrophic scar. It used to be fairly small which didn't bother me, then all of the sudden it grew tremendously! I figured it was because I had to take my earrings out and out them back in often for cheerleading. Just recently I had to take all my piercings out for my cheer competition and now because of the huge bump I cannot get my industrial back in. The bump hurts but it is colorless.
