Robin, I've been thinking about
you and praying for you, also.
My husband just had much shortness of breath, and did have fluid in his lungs. They gave him Lasix via IV, and it worked very well. We were thankful for how fast things improved. I hope it's something like that for you, too.
Will keep praying, and I know many others are praying, too. Do keep us updated. So many of us are wishing you the absolute best.
Hugs!!!
