Get your test results and review them yourself. I started looking at my numbers and when I spoke to my primary Dr about some of them, I got the same "you are fine" answer.
Numbers looked off to me so I went to a Pulmonologist and after she reviewed the numbers she ordered a few more tests. Come to find out, my eosinophil count was through the roof.
Sometimes it takes your attention and the right doctor to look at the right things.
