Hamster with infection keeps sneezing/chirping??

[luciillama]

Hi!
Our hamster, Silver, is a few months old and recently had to be taken to the vet as her teeth had grown in too long and started pushing into her nose, which resulted in her having a pretty bad infection (swollen & crusty nose, crusty eyes, poor baby )

We've been giving her antibiotics through a syringe as she wasn't interested in eating for the first few days, the medicine bottle says '1.00 x Septrin Paediatric suspension (100ml) per ml' and the dosage is 0.04ml every 12 hours. She's had it for 6 days now, tomorrow should be the last day.
She has improved a lot - her eyes are bright and no longer crusty & her fur is looking good. Her nose is still a little bit crusty and red but seems to be getting better (hopefully it will be all gone by day 7, I'm not sure if I should continue giving her medicine for just a couple more days if it isn't?)

The thing I'm concerned about is, she makes this small sort of squeaking noise pretty often which sounds a little bit like a sneeze, I'm not sure if this is from the infection she has or maybe a different infection entirely, and if so, is it safe to assume her antibiotics should help that? She does make this sound sometimes when I give her the medicine (I assume because she's not exactly happy with it, I haven't had a chance to fully tame her yet although she's never gone to bite me) but she also does it sometimes when she's sleeping, when she's eating, or just sitting and grooming.
I know they can chirp if they're happy or stressed, but I can't tell if it's related to that or if it's a sneeze or respiratory issue. I wouldn't assume it's respiratory as everything else about her looks fine and healthy (minus her nose not being 100% better yet) and she is getting more and more energetic & lively each day, and she is eating.

Could she be allergic to her bedding? We use Megazorb wood pulp bedding which has been fine with all of our hamsters so far. I'd like to try changing it to see if it helps (suggestions are welcome) but I'm unsure about doing it yet as I'm worried about stressing her out too much? Especially with what she's having to deal with already.

What do you think? Do I risk stressing her out more by changing her bedding now or wait until she's better? Could she just be a noisy hamster? Taking her to a vet is difficult at the moment with COVID-19, so I'm trying to do all I can for her at home.

Any help at all would be greatly appreciated, I tend to worry a lot and I think that sometimes clouds my judgement a little!
