I m not sure what specialty I should ask. July 25, I had my upper left lobe removed due to a nodule. Also had a 5 lymphnodes removed. Cancer was contained to only the nodule 1.2cm. I was released 3 days ago. Today a rattle or gurgle of sorts has started. It does not cause additional pain, nor does it make me short of breath but it does worry me a bit. I ve read lots of blogs, etc., and most seem to feel that it is normal and to keep walking and doing breathing exercises. I will call my doctor tomorrow but am up and worried so thought I d ask.
