No, this is not a new fashion statement. I now have four of these teeny gold studs in each ear until they fall out. (The one you can't see is in the top of my ear.) This is the latest form of acupuncture we're trying. I've been trying to do some research on it, but haven't found much. Maybe I'm just using the wrong search terms.
Insertion was painful, and they're still very tender right now. I'm not sure how I feel about it yet, but I'll let you know how the weekend goes. In the meantime, wish me luck. Who knows when and where one might choose to fall out!
Here's an article I found that mentions it. Pretty interesting actually!
