Bellybutton ring sticking to skin?

I've had it pierced for over 6 months. I had no problems for a while when I changed it but then I snagged at the piercing and it was swollen for a while. i changed my bellyring back to what it was pierced with and it healed, but now my skin around the piercing seems stuck to the bar and I can't freely move it. it doesn't hurt or anything I'm just worried it's going to be like this forever??
