Lump in Throat after Septoplasty/Turbinectomy

It's been 6 months since my surgery for septoplasty and turbinectomy because i've always had problem breathing through my nose due to a large turbinate from my allergies, after the surgery i can breathe through the nose but i have a constant feeling of my throat being stuck with mucus and have to constantly force it to go out, it's the most annoying thing i've ever experienced and it won't go away.

I did a endoscopy because it could be a laryngopharyngeal reflux but they found nothing, so it is probably post-nasal drainage, i took antibiotics (levofloxacin) and a vaccine and they showed no result.

I don't know what to do anymore, i honestly could not find any correlation between septoplasty cirurgery and the throat being sticky with mucus, doctors don't seem to help me and i'm starting to lose my mind.

Sorry for my english, i'm from Brazil and most of it was typed with google translate.

(Also i seem to have a little bit of constant asthma after the surgery making it harder to breathe)

Can anyone please help me.

Just curious if you have received some relief
