Thanks for your previous reply, I sincerly appreciate it. You informed me that my chest xray' are not typical of Pul Fibrosis. I was worried that the scarring or bibasilar atelectasis had slightly increased, therefore seeming like Pul Fibrosis. What are the typical xray findings of this disease? Does it normally start in the lung bases? I worked in a factory for 10 years was was around grinding dust and metal dust. I also breed parrots for a few years. In addition I have had pneumonia serval times throughout my life. I dont have a appt. with a Pulmonigists until 6 weeks and really worry about a terminal lung disease. Since I quit smoking, I have started running 2 miles every other day to strenghten my lungs. Even though I am breathing hard after the 2 miles, I am not without breathe. I know that no one can quarentee that I dont have IPF, additional reasurrance is always nice. Thanks again for your help!
