Started out as pinkish...then next day streaks of blood, back to pinkish....then now again...blood....There has been so many complecations from this fall ...is this just another one? [/INST] Thanks for your question on Chat Doctor. In my opinion you are having lung infection.  As Chronic bronchitis patients are prone to lung infection and lung infection cause worsening of chronic bronchitis, increased breathlessness, yellowish phlegm, blood in sputum etc. So we have to rule out lung infection first. So get done chest x-ray to rule out infection. You may need antibiotics too. So consult pulmonologist and get done chest x-ray. And I don't think it is complication of your injury. </s>
