I Had a Septorhinoplasty Done in About a Month. I'm Told I Have ETD Now?

I'm just wondering as if how long will I have to live with this! Cuz thers no fluid in my ears no hearing loss no pain but I just don't feel normal constant pressure in my ears clicking noise every time i swallow, post nasal drip! tried flutinoase, afrin antibiotics were prescribed to me nd nothing seems to work , I've done saline rinses the whole nine yard. I've recently looked up balloon sinuplasty and I'm wondering if I should be giving this a thought!
