I was accepted to do a headache study call myst II,  but got kicked out for having too many ha's.  They only wanted people with less than 15 ha's per month.
   I wanted to know if anyone on this site has heard of this the study was called myst II, or PFO study.  There is a valve in the heart that they have found too be open on most ha sufferers, in the study itself they closed that valve this valve is supposed to be closed but 25% of the population it stays open,  and is open on 75% of people that have ha's with aura.  The study was done near chicago, I cant find myst II online but you can search pfo online and find it.
  Has anyone here had this done, and if so does it help for CH???????
