ooohhh sorry, meant to say...symptoms come out of the blue. Foods don't seems to trigger them. It's a different feeling to heartburn or similar. Another way I could describe it is this.....sometimes it feels like I have a sponge inside my chest that is filled with water, sometimes it feels like my chest is full of jelly wobbling about. I know it's a pretty lame description. It's the closest to how it feels tho!!
