respiratory tract infection

[pony&cow]

my horse has been ill since thursday last week. Her glands (lymh nodes i believe) are swollen more so on the one side, she has a runny nose mainly clear fluid occasionally slightly snotty, weepy eyes, is lethargic and not drinking (although weeing and pooing), she is eating plenty of lush grass but not interested in any other food, her temperature is normal, she hasnt got a cough.

She has had a 5 day course of pen and strep and bute.
She has tested negative for strangles both on a swab and blood test.
The vet has suggested give the antibiotics time to work.

Any opinions? ideas?

I would have expected the antibiotics to have worked by now, is she on anything else to clear her airways?
It actually sounds like a form of hay fever from the symptoms.

No she's not on anything else. vet said it can take 2 weks for antibiotics to take hold of the infection????? I dont know?
Vet suggested just give her more time and plenty of tlc but im worried theres no progress.

any experiences anyone?
