Sorry, I am a noobie, so take what I say with a pinch of salt, but..

You havent duplicated something accidentially and its still there?

You havent used a curve tool and bits of it are left inside still?

Have you tried opening the scene and dragging the main mesh of the body only to the side and see if something is left behind, then deleteing that?

I'm sure you've thought of these already though!!
