Hi, I m itssel. I have a question from something that s been happening to me for a while now. It s this feeling in my chest and throat. It s as if I had something stuck in it. In my chest, it feels like its being sat on. It feels really tight. Also I have this horrible pain in between and under my ribs. It all gets worst when I lay down. It doesn t let me breathe. Also, my heart is just racing, and suddenly it goes back to being slow. It hurts really bad when this happens. It s been going on for a while now but each time it happens it just gets worst. I also get nausea. I dont think this is normal or a good thing. Your help would be appreciated, thank you.
