Before the parasites were removed, everything hurt so much that I stopped noticing. I don't know why they're still there.
But it doesn't hurt now. They're just...kind of there.
[maybe they fused with her bones or something equally useful and nice.]
They're annoying, though—I can't wear a lot of clothes.
