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.
