Well now I don't know about giving pain killers, but my daughters cat was sick one time where you couldn't even touch her. The vet gave her some stuff called Ketoprophen. Not sure that's how you spell it but when that ran out my daughter gave the cat a quarter of an Ibuprophen human pill.
I'm sure you've quarantined you duck so it can rest so I won't suggest that, but you might do a search on a Duck site and see what it says.
I wish you and your duck well,
Rancher
