thanks @merpreb so I can probably rule out MAC (unless I have hairy cell leukemia and I think that would come up in blood tests?) what about cvid? (Assuming the next ct scan I still have the infection, what would you call pneumonia that responds to antibiotics but keeps returning or a small portion remains? ANd what if the infection was greatly reduced by the antibiotics but a vestige remains? Do I just continue with another round of antibiotics?

@merpreb had my allergy tests. I didn't react to any allergens. Ironic, I'm so healthy, except I ruined my lungs. They gave me one spirometer test- blowing out as hard as you can. They use a visual, a tree with leaves with the goal to blow off the leaves. I was able to do it easily, so it must of been easy.
One productive thing came from the exam: the doc said he wasn't surprised I got pneumonia 2x because the vaccine I got only protects against 1 strain. He sent me for a blood test where they test my immune systems reaction to various pneumonia strains. He claims that will tell them the type of vaccine to use when I hit 65 (3 more months), and that vaccine will be more likely to succeed. Have you, or anyone in th group, heard of that type of blood test.?
