Dear Doctor, Occasional bloody sputum since 2017. Several times tb test failed. Ent checked no issues. No stomach issues.  At 2021 i got handful of blood after heavy cough from chest center after I woke up with shortness of breath, fainting and temporary right hand paralyse for 10 mins. Doctor said it's like TIA and took Chest Ct which showed cavity in lung. Checked with many pulmonologist they said either leave it free till it get developed as cavity is very small or do bronchoscopy. I have taken CT now, it shows pulmonary artery touching cavity. Pulmonologist says just do bronchoscopy, find the issue of cavity, take medicine My friend brother MD pathologist says, since pulmonary artery impacting the cavity when you get a heavy cough it will cause internal bleeding leading to mortality 50 percent . Should I correct the artery? Or just take medicine after bronchoscopy finding the issue for cavity. It's more confusing and complicated.
