yes I've used that. Let me give you an example. As you know when your first diagnosed it's just a whirlwind of information coming at you, I really don't remember who said what or when. As I said I had my chemo and then the surgery. Now I don't know if I was told or not but I could not lay down I had pressure on my chest I could not take a deep breathe I lose it! Instead of saying it's my lungs adjusting after surgery they thought it was my heart which is understandable I went to the EU acouple of times before one doctor sat me down and explained that my space where my lung was is filling up with fluid he said there was not alot of fluid it's just your body has to get use to the empty spot. That's all I needed it's make sense but I was just in a panic, mayo never warned me of that it scared the crap out of me
