Is my ear infected? (Pierced ear)?

My ear lobe has been pierced for around two years now. Everything's been okay until recently my hole began swelling. I don't know what's wrong. I started taking off my earing when ever I went to sleep and it seems to be getting better, but it's oozing out this liquid that turn sticky and orange when it dries up. A lot of it ozz' out. It's very itchy and I feel a lot of pain in my jaw, right bellow the pierced ear. Is it infected? I do clean it and my earring is pretty new, real silver.
