Hi, Ive been noticing light crackles in my right lung base, but only when I lie down in a stretched position. They also happen if I hold my breath and push on the center of my chest. The crackles come and go, and if I shift my position even a little, they disappear. Im not experiencing any chest pain, and the crackles are occasional. Should I be worried about this or is it 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.
