Hello all. First time here. For the past 2 months I've been having strange symptoms. It feels like there's a bubble, moving in my chest, over my heart and into my throat. when this happens my left arm and leg get numb and cold (usually starting right at the joints) It very painful. There are times when taking a deep breath makes it feel like my heart is being Squeezed following this is getting dizzy. It also tends to feel like there's trapped air but when I do manage to burp there's no relief just the same feeling of something being lodged in my chest or throat. Oddly enough it feels more like they're something trapped on the right side of my throat . For years I've been very aware that I suffer my anxiety but this isn't it. I was in the ERA couple of days ago had all the tests to rule out all the "scary things" and they found nothing. Please someone tell me I'm not alone in this.
