usually fluticasone (Flonase) steroid nasal sprays don't have to be weaned when you need to stop it.
however, long term steroid nasal sprays can suppress your immune system in your throat
and can increase risks for throat candada fungal throat infections which can cause sore throat
you should have a doctor look down your throat
there are antifungal mouth washes like Nystatin mouth washes and antifungal clotrimazole prescription throat lozenges which can kill fungal infections in your throat which could help your symptoms.
talk to your doctor about this possibility of having a throat fungal infection.
let me know if you have other questions.
