Hi all,
I am going to try and post at least once a week.  Hysterical idea; I know.

Found this article that offers the best explanation I have found on my EM disorder. I do not have the hereditary type, but the rest applies to me.  The Article is titled Pain Gate. Short read and will explain what that my disorder is a sodium channel thing connected to my DNA.
Enjoy the read.
