Hello and welcome to the forum.  I'm sorry to read that they have some findings in your lung.  I do want to say that often when things are seen, they are harmless, benign and everything is just fine.  What does your doctor recommend as a next step for you? Please let us know?  Here is some information regarding suspicious findings in the lung  https://www.webmd.com/lung/benign-lung-tumors-and-nodules#1  

As to a swollen lymph node in the lung, that can be due to infection.  Have you been sick with any respiratory illnesses lately?  
I have been fine. Lung ct this week. Thanks for your input.
Please let us know the findings of your ct .

Perifissural nodules (PFNs) are well-circumscribed, smoothly marginated, commonly triangular or oval nodules in contact with or closely related to a fissure. These typically represent benign intrapulmonary lymph nodes.

In contrast to pulmonary nodules which should be followed according to guidelines published by the Fleischner Society, intrapulmonary lymph nodes do not require continued surveillance.
