I've been noticing these black hairstreak-like things in my phlegm and it's freaking me out a bit. Plus, I've got this mild chest discomfort that won't go away. What do you think this could be?
The presence of black streaks in your phlegm, along with mild chest discomfort, could suggest a possible issue with your respiratory system, such as inhaling environmental pollutants or smoke. It's important to consult a healthcare provider to rule out conditions like a respiratory infection, bronchitis, or more serious issues.
