For one, don't push on it, that's probably what is making it hurt. I had my belly button pierced and it takes a long time to heal, what you're experiencing sounds normal to me. Try going to the store and getting sea salt (put it in water), or going to another piercing store and seeing if they have the sea salt spray. It cleans it and you don't have to put anything else on it. By the way, there is a possibility that the AD ointment is getting into the whole and that is what you see coming out.
The piercing is supposed to give off a little discharge and and it will crust onto the ball. You should be moving it around when you clean it to make sure that you are cleaning the inside as well. Definitely do the sea salt thing, soak it for 15 minutes 2 times a day. If the fluid that is coming out turns a funny color or you start to get an abscess you should see your dr. Just make sure you are following the instructions that the piercing shop gave you and you should be fine.
