I'm a bit worried because I had COVID about three weeks ago, and my doctor suggested spirometry exercises for my lungs. But I've noticed that when I do spirometry for about 2 minutes, my SpO2 levels drop to like 92, 93, or 94. If I wait for 5 minutes after that, it goes back up to around 98 or 99. I also tried a 6-minute walk, and my SpO2 seems to stay around 96 to 98 during that. Is it normal for spirometry exercises to drop my SpO2 so much? Just for reference, my chest CT score was 12.

I'm a bit confused about my mom's diagnosis. Her CT scan showed something like patchy airspace acinarization and some nodular radio opacities, and she has prominent bronchovascular markings. The doctor said she's got tuberculosis and put her on this Rizorine kit. But what's really bugging me is the doctor mentioned it's not contagious. Is it common for TB to be non-contagious, or could there be some misunderstanding here?

Yes it is not contagious,as we all are vaccinated for it,but if you are weak it might infect you,be safe and follow hygiene practices

I was wondering how long a fever usually lasts after starting treatment for TB. My wife began her treatment with AKT 4 on March 2, 2017, but she's still getting fevers up to 101 once a day. Is this normal? How long does it typically take for the fever to subside after starting treatment?

it might take 3-4 hours after treatment started

I'm currently on tiotropium, taking 1 capsule a day for inhalation, along with avessa 250 rotocaps, oxybro capsules, and glemont f capsules. I'm a bit worried and just wondering if any of these could be harmful to me or if they contain steroids. Could you give me some info about these medicines?

Continue same treatment as advised by the physician.
