[|Human|] I have had a cough for about a year and here recently I see that I cough up blood in the mucuse...it s not a lot but enough to make me wonder. I worked at crystal sugar and was subject to breathing lime dust among othere dusts. Could this possibly be linked?
[|AI|]  Thanks for your question on Chat Doctor. I can understand your problem and situation. In my opinion you should consult pulmonologist and get done1. Chest x ray2. PUT (pulmonary function test) to rule out chronic lung infection and chronic bronchitis. Yes, you are right about crystal sugar and lime dust. Chronic exposure of both of these can cause pulmonary diseases. And blood in sputum (hemoptysis) is something, you should worry. It suggests worsening of underlying lung disease. So better to first diagnose yourself and then start appropriate treatment.
