I am also having the feelings described. I want to scratch around my heart all the time, as it is so itch..cannot of course
but I would love to know what is causing this feeling..it is in my left shoulder as well. This feeling of air been around my heart..and me wanting to scratch, and then my left arm goes all heavy on me. I had a ecg a while back, because I was having sharp shooting pains in my chest while breathing.. I was told all was ok, and to take voltaren. it did help for a bit. But now this itchy feeling has started..any ideas?
