Most of the time its just an annoying discomfort for a few hours after I eat. I've had a couple major attacks that felt like a pair of hands trying to make balloon animals out of my gut. Some of the worst pain I've ever felt.
My doctor said that GB usually has some severe pain. I get discomfort, not really pain in that area (upper right quadrant) periodically. So he said it probably isn't GB. Said basically don't worry about it.
