I had a abdominal CT scan that showed a single pulmonary nodule in my lungs, but was blurry. I fallowed up with my family doctor months later who ordered a chest CT scan with contrast that confirmed a single pulmonary nodule, however the nodule had changed location. She ordered a battery of blood tests to be done. Any idea why it could have changed sides? The doctor did not seem certain at all as to why it would have moved. I also have a very swollen lymph node under the left side of my jaw.
