hen with swollen cheek that wont go down

[Tessanator]

Hi, I have a young hen whom I seperated with another that had respiratory issues. The hen with crackly breathing is fine now, back in coop. But this little gal still has swollen face. They have been on Pennchlor64 for 7 days. The one who has swollen face in pic had 7 days of anti-inflammatory injections. Applying vet Rx on face and putting it and colliodal silver and vitamins in water Face still swollen. She is eating and drinking and laid an egg today. But, still looks terrible. Anyone know what to do next? could it be a parasite in throat or sinus? She is shaking her head too.... Seems like losing feathers aroung cheek. The rest are fine, but she just cant seem to shake the swelling. Any input is appreciated.

It could be pus in the sinus cavity, chicken pus is hard and needs to be removed manually unfortunately

Can you get some photos of the inside of her beak?
Have you looked in the ear for any pus?
Any bad odors?
Any lice/mites?
