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'm really struggling with breathing properly because it feels like my lungs aren't getting enough air and my nose is almost always blocked. This has been going on for a few months now. Sometimes I get chest congestion too. It's affecting my sleep a lot since I wake up with a heavy head and I feel sleepy and drowsy the whole day. Could you suggest what might be going on?

I've been experiencing some light crackling sounds in my right lung base, but only when I lie down stretched out. Even when I hold my breath and push in the central lung area, the crackles tend to come and go. If I shift my position even slightly, they disappear. There's no chest pain, and these crackles are just occasional. Should I be worried about this, or could it be something serious?

The light crackles youre experiencing may be related to mild lung congestion or postural changes affecting air flow, which can be common and not usually serious, especially if theres no chest pain or difficulty breathing. However, if symptoms persist or worsen, it's a good idea to consult a doctor for further evaluation.
