The Effect of Dog Biting on My Ear

I had my ear bitten off by a dog. It's been sewn back on. And then I said my nose bitten off by an parrot. Long time ago. He did a lot of my piercings and that one was like, and he's like, oh, because it's hitting like it's a good thing. Mine is more the after. Six months after sleeping on it. It hurts me too. This one up here in the high cartilage took forever to heal. It still hurts. But I did it really? Can you not?
