Dried pus/ball of skin came off while cleaning new piercing? Normal?

I was cleaning an infection around a fairly new piercing and I noticed that it looked a little off under the earring, so I took it out and the skin was a weird colour right under where the earring was. I poked at it a little and then noticed it came up a little. I got some tweezers and it pulled right out. It was this little whitish o shape, kind of like a small ring with a hole made by the earring. It left an open sort of red gap where it was before I pulled it out. Now I have a little bit of a gaping hole in my ear, but it hurts a lot less, and basically back to normal. I cleaned the blood and the excess pus away with antibiotic. I've gotten infections before, but nothing like this. Does anyone know what I pulled out of my ear or if this is at all normal? If I keep normal sized earrings in will the hole close to a normal size?
