Well had a chest ultrasound and there is fluid in my lungs. Don't know how serious it is yet as I haven't seen doc in two days because of all the other appointments and things I have had to get done so I don't know what the plan is. They have been giving me lasik (diuretic or water pill) since day one and I have been using my breathing thing whenever I am awake. Will this help the fluid problem unforntunately I haven't been able to cough anything up.
