Do any of you ever get pretty intense sensations in your chest, like a cross between a chest cold feeling and heart palpitations? i know that is a terrible description, but it's so hard to explain. if you've ever lived by the ocean, you might know a sensation called "sea cough" (not really a cough) - well it feels like that sort of when you breath in. Was having it SUPER strong today - very strange feeling because it doesn't develop into a cough or a cold or anything. it just kind of sits there in my chest. Figure it's some kind of cleansing process, but curious about anyone else's experience with it. sorry for the pathetic attempt at a description!
