Any piercers or people who know a lot about piercings out there?

I got my belly button pierced a year ago this month. I still get "crusties" and green stuff still comes out sometimes. also, the thing that irritates me the most is that it lays on its side a little it's not facing all the way forward. The piercing place that i got it done at did a great job, this is a direct result of my own laziness. (please feel free to shy away from telling me what i already know).. It doesn't hurt it just isn't pretty like it used to be. Also, i think it may of healed sideways because i sleep on my stomach, anyway can i possibly fix it so it doesn't lay sideways? what should i do?
