Hi thanks for contacting HCM ... Let me know you your bleeding is because of respiratory problem... The opacity could be from pneumonia or bronchitis like condition.... This is called hemoptysis in which cough with blood originated from affected lung expectorated through mouth.... Your sputum examination should be done for rule out etiology .... The possibility of bacterial pneumonia , fungal infection , tuberculosis should be ruled out and accordingly treated.... For bacterial pneumonia or bronchitis you needs to be given antibiotic.... If needed HRCT can give detail about opacity. So consult pulmonologist for examination with keeping this in mind .... Take care ... Hope your concern solved .
