Oh, you won't drown. There's very little actual material in there. If you could magic it out intact to look at, it would probably be the size of a few coffee grounds. Most of what you see in your picture is just swelling. Given the amount of pain PK's describing, his was likely a LOT bigger than yours, and he didn't drown. It's amazing how much a tiny thing can hurt, when your body isn't happy with it.
