For the past few days my stomach hurts. I feel it when I take a deep breath or push on it. It doesn't matter if my stomach is empty or full but it does seem more uncomfortable when I eat something. I haven't gotten stuck in the past few days or vomitted, and I am sure my band hasnt slipped as I am having no issue with eating. I did do a great deal of heavy lifting moving around furniture but thats about it.

Should I be concerned? Has this happened to anyone else?

You need to contact your doctor. You may have a hernia. Maybe not; but if you've been in pain for several days and it hurts to breathe deeply you need to get checked out. You can start with your banding doc or your primary; either one should be able to help you figure it out.

I agree. Check with your doctor. Maybe it's nothing. But if it is something you want to get on it right away. Let us know what you find out.
