Oh my goodness, David - with answers like that nurse gave you, no wonder you are not impressed with the treatment and lack of clarification and proper answers to your questions! I'm so sorry this has been so rough on you and Linda. Wish I could be there so I could go yell at somebody! Keep bugging them for proper answers and get as many people involved to help you until you do! Do they by any chance have a patient advocate that can help you with information you need, or get a meeting going with the pulmonologist? You are such a great caregiver, David - but there are times when caregivers need a little help, too. Hope you and Linda get some relief soon from all this and that things improve.
