Hi, I just wanted u to know I have the same diagnosis's and the same exact thing happened to me, but I have only had it 1 time and that was this past Monday morning. I was so shocked!! tho Mine lastes a few minutes and I was so scatter brained all morning. since then I have had alittle pricking sensation in my chest and thats is it. Have you ever got an answer as to what this is all about? I was shocked as I kept reading your article, because it was an exact thing for me.
