I have an appointment next month for a DXA scan to check my bone density. I think I'm actually still below the age where it's generally recommended, but I recently learned that the meds I've been taking to manage migraines for almost 20 years can affect bone density, so I want to know where I stand.

Does anyone out there know what this test involves?

The instructions on the doctor's order say to avoid wearing clothing with metal snaps, buttons, etc. Does this mean it's similar to an MRI? I have a pierced belly button and I'm wondering if I'm going to have to take the ring out before the test. I've never actually taken it out before so I'm worried about being able to get it back in afterwards. Although, I've been thinking about changing from a ring to a banana bell for a while now, so this might be a good time to do that.
