We are not asking for 100% improvement in the lungs oxygen levels, but any small improvement would be a great help. My medical provider says it will only get worse with age. I have received absolutely no hope or help from the pulmonary Doctors that I have been seeing. What can I do? I don't even want to go to their office because of there lack of support. I keep going back because my husband insists that I see them! Sheila rbrnger@aol.com
