Hi K_Nelson, 
  
 I woke up one Saturday morning with a "bad one" coming on, I'd had enough and heard Daith Piercings worked, so I went down to the local tattoo/piercing shop and had it done there and then. 
  
 It sounds dramatic, but it cleared the migraine within a couple of hours and all my "secondary symptoms" decreased immediately.  I felt great.  In fact I hadn't realised how much suffering with migraines had affected my moods until they were actually "gone". 
  
 Unfortunately the piercing didn't take for me, so, I had to remove it a few months later and within a couple of weeks my symptoms started coming back again and they increased in frequency and intensity. 
  
 So, at the moment I don't have a piercing, but seriously considering trying it again!  I don't know the science behind any of this but it worked for me and I hope this helps someone else. 
  
 Regards, 
  
 Dan
