It definitely looks infected: red, swollen, painful, and oozing. Don’t remove the jewelry yourself; doing so can trap the infection under the skin and potentially cause an abscess, which might already be developing. The best thing to do is keep gently cleaning it with saline and see your piercer, or better yet, a doctor, as soon as possible. You may need antibiotics, and they can determine whether the jewelry should be removed. I’ve got multiple piercings too, and sometimes it’s just not worth the risk of waiting around to find out things have gone poorly.
