<human>: For almost a year every time I cough up my spit I will see black cloudy stuff in my spit. It only happens sometime like whenever it wants to show up. I don t smoke at all. I am worried that it is something more dangerous. Please respond back as soon as possible. If you need more information please contact me at my email. Thank you.
<bot>: Thanks for your question on Chat Doctor. In my opinion you should consult pulmonologist and get done chest x-ray first. As black phlegm can be seen in1. Long-standing hemoptysis. 2. Fungal infection.3. Coal particles in trachea etc. So better to first rule out with chest x-ray. And if x-ray is normal than get done bronchoscopy and lavage fluid analysis for above-mentioned causes. So better to consult pulmonologist and get done chest x-ray and bronchoscopy and discuss all these.
