I was just at the doctor a couple of times in November. Turns out I had a bronchitis, possibly with a bacterial superinfection.
So I was at the doctor to
Check if my lungs were affected. is there a danger of a lung infection?
Do I need antibiotics or should I sit it out?
Get a doctors note (I was on sick leave for three and a half weeks)
This is nothing I could google. I actually did google and did not find bronchitis as an issue, but cold, influenza, and lung cancer. Google does not know how my lungs sound when I breathe.
So of course you should ask your doctor and not the internet.
