I'm really concerned about my oxygen levels; my SPO2 seems to fluctuate from 89 to 99, and it's usually more stable between 92 and 95. I also have frequent throat infections because of sinusitis draining into my throat and occasionally deal with upper respiratory infections. Could these issues be affecting my oxygen levels? My recent master checkup was normal chest X-ray, ECG, and echo all clear. Ive been using a fingertip home pulse oximeter for measurement. Lately, the throat infections are happening more often. What should I consider or do next?

Frequent throat infections and sinusitis can cause fluctuations in your SPO2 readings, especially with post-nasal drip affecting your airway. However, since your chest X-ray, ECG, and echo are normal, its less likely to be a major underlying issue. Keep monitoring your symptoms, and consult with your doctor if the infections persist or worsen.

I've been diagnosed with bronchitis after checking my x-ray, and I've taken a lot of antibiotics, but now I'm having pain on the lower right side of my chest. The weird thing is I don't have any cough at all. I've just started taking Prentiss 800. What should I do next? Any advice would really help.

it's gastritis because antibiotics will cause gastritis sometimes

I've been noticing this weird poopingcracking sensation in my lungs when I'm sitting, and it seems to come and go without any warning. It's been bothering me because I'm not sure what's causing it. Could this be something serious, or is it just one of those random bodily quirks? Would love some guidance on whether this is something I should be concerned about.
