Sorry this is happening, because it's scary. But it doesn't mean anything. We all know that such symptoms can not be relied upon to mean anything at all. They're just there, and we don't know why they happen sometimes and not others. It's so hard to hold on to that knowledge when we're in the middle of scary symptoms, but it's still true. Big hug to you. Is there something you can do help assuage your nerves? Something that you enjoy that relaxes you? Watching a movie, knitting, meditation, whatever will help you relax for YOU, not to try to get rid of those symptoms. I'm rooting for you, hang in there. Keep us posted on how you're feeling. Big huge hug.
