DS1, 22yo has a cough. He's had it for a couple of weeks, I get regular updates on the phlegm he's producing - lots but clear.
At no point has he seemed ill in himself, he just has an annoying cough.
The last few days he's complaining that his chest hurts, sharp pains. I've said it will be muscle strain from all the coughing, he's being much more dramatic about it. His GF thinks he should see a doctor and I'm afraid I've been a bit don't be ridiculous.
If it goes on for a week or two, maybe, but surely he doesn't need a doctor now?
