I try the breathing but it doesn't always work. I had one of the worst attacks the other day at work and like yours Perna, it was brought on by absolutely nothing. I didn't have anything that was stressing at the moment. As a matter of fact it was an easy day in the office. I first felt my feet start getting warmer and it worked it's way up my entire body. I started to sweat and shake and all I wasnted to do was run out of there. My thoughts were racing as fast as my heart so as calmly as I could I got up and went into the bathroom where I had to stay for 20 minutes. I thought I was going to pass out as I walked down the hall. I work in a hospital so I guess I was in the best place I could've been but I don't talk about my condition with my co workers so I was even more frightened that this was happening this bad at work. This is starting to really affect my general way of life and I don't understand how these attacks can happen and there not be a solid medical reason for it.
