I'm trying to understand my recent x-ray results which mentioned 'right apical PTB of undetermined activity.' I'm a bit concerned because I did a sputum test and it came back negative for TB bacteria. Also, I have no TB symptoms and the last time I had this disease was 14 years ago. Could this be something serious? What should I be looking out for?

The X-ray result indicates a past, likely healed, tuberculosis (TB) infection in your right lung, with "undetermined activity" suggesting no current active infection, which is supported by your negative sputum test and lack of symptoms.

I've been yawning a lot and feeling like I constantly need to take deep breaths, almost like I can't get enough air. It's really weird and a little worrying. Is this something I should be concerned about? Could it be related to stress or something else?

I'm trying to make sense of a chest ultrasound report and figure out if a pleural effusion should be drained. Is there any way to tell how much fluid is too much, or any specific measurements I should be looking for? I'm really unsure about what indicates a need for drainage.

it should be done clinically

I've been really worried because my mom used to feed pigeons on her balcony every day, and they pooped there for a whole year. We stopped doing it but now I'm concerned. Could this be why she has lung nodules now? Last year her CT scan only showed fibrosis, but this year there are lung nodules, and the largest is 9mm. Could feeding birds have caused this? I'm really looking for some advice here.

Pulmonologist opinion is advised to the patient.
