@ninjanana ... The bronchoscopy is very helpful and routine. Try not to worry. If you get anxious, the doctor will relax you a little more as happened in my first test. The second and third were easy after I'd learned what was happening. No meds needed. This test is the best way to see what the structures actually have going on.
I've found that the nurse practitioners are better at listening and explaining. You are in good hands.
