I Have Had A Persistant Non Productive Cough For The
Please do a plethysmography test
Detailed Answer:
Hello and welcome in Ask the Doctor
I can understand your concern
As you explain the situation usually small.nodules in the lungs and especially if they are peripheral do not cause cough and in my opinion this was the reason that the pulmonologist has not given so importance to them and I agree however it would be better for me to have the chest CT images to see them by myself and to be more correct with you.
Nevertheless if you were my patient I would recommend you to do a plethysmography test to rule out also the sleep apnea which causes sleeping problems.If it is positive than the treatment is another one . Please discuss with your doctor for the above
Hope to have been helpful
