Hello. I had a pneumonectomy four weeks ago for atypical carcinoid tumor. Prior to surgery, I had a terrible, persistent cough. Now I still have a slight cough. I thought the cough would be gone since my remaining lung has been clear in all of the X-rays. Is this normal after this type of surgery? I am using the I inspirometer and walking every day. (I will ask at my appointment later this week, but am becoming anxious.)
