Hello, Thanks for the query to H.C.M.C.
I think you are talking about "calcified spots " in the X-ray chest.
Calcified spots in the lungs on an Xray are called granulomas and these are absolutely normal.
Calcified spots are also indicative of old lesions of some infectious disease , that's why doctors reported unfit to you.
You are not unfit and consult a radiologist
about these calcification.
Good luck. Dr, HET
