I got my nose pierced and about three weeks later I went in and got it changed to a ring, but I often have to change it for work. And I have been noticing this reddish-purple scar, and it's been sort of growing somewhat. At first I thought it was a blister because of my nose ring moving a lot, but it won't pop when I pick at it, and it's slowly (like really alowly) getting slightly bigger. What do I do to get rid of it?!
