I got mine done in May, for migraines and it is cute!! LOL.....not helping at all! :(

I had both mine done in Feb. I don't really get migraines anymore. Not sure if its from that or herbal supplements I'm on. Even so I love mine. Though I recommend getting a snapped earring for it. The balls fall off sometimes n crazy hard to put back in
