I had to google daith piercing, as I didn't know what it was. There are lots of documents that say it doesn't cure migraines. I can't see how it would anyway. Take it out if it's bothering you.
thanks for your feedback,its trial and error with everything and I have heard of it working for people,if you suffer from migraines you will try anything,and you cant take it out unless you go back to shop,im an optimist so giving it a go.
