hey, ive had mine done for nearly four years now and have never had any problems with it since it healed. However, when it was healing i think it got a bit infected but i used ear piercing solution on it and also savlon, and it soon healed up. But the fact that yours hasnt healed suggests you have some sort of reaction to the belly bar, whether it's the piercing or the bar however i dont know. DONT take it out for ages because as others have said, it will close up and be really painful trying to put the bar back in. Have you tried a more expensive bar? Could just be you need a richer metal....If you take it out it MIGHT leave a scar but it depends how infected it is and how it looks at the moment. Someone at my school got hers really badly infected and had to take the bar out, and she ended up with the most horrific scar!! So be really careful in choosing what you do, and perhaps check with a qualified piercer...
