@cryptopie are you attempting breathing exercises? It can help naturally push fluid off lungs. Ive used it before and is somewhat effective. Cant replace a Dr, but can sustain you until you see one. Sometimes plueracy (spelling) inflames lungs, and fluid builds up. Idk not a doctor but speaking from experience.

I hope you can get to a new center. If youre being treated for anything, a little compassion and empathy do wonders for patient health.
