My X-ray results are minimal fibrotic scarring in the right uppuer lung, no parenchymal infiltrates seen, what does it mean? Did I have an illnes?

X-ray results . Discuss this with your dr so he can show you on the x-ray what it is and where, while you explain your history.
Probably. The scarring is a result of previous inflammation usually from infection. The location of the scarring on the x-ray raises the possibility of exposure to tuberculosis. You should get a TB skin test if you haven't received bcg. Go see the doctor.
