Runny nose+choking on phlem?

[Calluna]

The thing you would have to look for is that the fluid isn't going onto his chest... watch for wheezing, loud breathing, rattle, vibrations when he breaths that kind of thing... Also watch him to see if he's pulling at the ears...

He has been pulling his ears but I had thought he was just tired as it's not all the time...
*off to have a listen to his breathing*

ETA - Breathing sounds ok, he's breathing through his mouth though.... Which obviously makes sense since his nose is blocked lol
