Hi Sandy..I havent had the problem with fluid on the lungs as such, well, I did have for a while after a Biopsy on my lung caused a Hemathorax, but only for a few days after they drained the lung.I have a Tumor in my upper right lung that was about the size of a large "Egg" and was putting stress on my wind pipe, and I found two things that helped. One was simply taking the puffer "ventolin" helped ease and open the wind pipe(Always check with your doc first), and the other was to use a Steam Vapouriser at night with Eucalyptus oil in it ( it also helped because of the humidity up here in the north) I bought mine from the chemist and was relatively cheap, I hope this helps
