I was around 13 when I had my first migraine. A solid block of pain on the right side of my head. That occasional migraine became more frequent over the years. I had a headache 24/7 in one specific place in my head.
In my early 30's, after blood tests, food elimination, x-rays and finally an MRI I was told that I had Chronic Daily Migraines.
Most days were 6-7/10 pain. Those days that were 10/10 I perfected the art of lying down and breathing in such a way that I barely moved. Noise / light were never an issue, the pain got worse when I moved.
Then I got a daith piercing.
I had read that a daith could help.
I got the daith ~14 years ago and I have not had any sort of headache since. Both my daughters who had migraines got a daith and they too have no headaches.
I get the sample size is not useful, but if you have migraines, go into your local proper piercing studio and ask for a daith - they will almost certainly reply "On which side of your head is the pain?"
