I was bothered by post nasal drip. My allergist ordered Ipratroprium, which works really well. It’s a nose spray you take when you need it.

I had a sinus infection March 2020, could've been covid but no fever or symptoms besides sinus trouble. I called the doctor and they order antibiotics over the phone. That didn't really help. Called back a couple weeks later and they ordered stronger antibiotics. These didn't really help. Since then, I have had tons of mucus and sinus pressure in my head and I am constantly clearing my throat but nothing comes up. My friends say I sound like an outboard motor. My primary care sent me to an ENT and he immediately ordered my to have my nasal turbinates reduced even though they were only slightly swollen. Fast forward to April 2021, I received the Pfizer vaccine (two shots two weeks apart) which I regret. I don't recall having throat clearing before I had the vaccine.
Anywho, I am so lost for options that I am uncertain if the turbinate reduction procedure is actually causing the constant PND and throat clearing.
My family and I also moved into another house in April 2020. The house was 4 years old one owner home. They had cats and I have had allergy testing done by two separate allergists, both blood and skin. I have never had allergies. I was prescribed Azelastine twice but it did not help. I went to a second ENT Feb 2022 after having a CT Scan of my sinuses done. He said that my sinuses were "Not Perfect", and recommended changing my lifestyle (no caffeine, alcohol, spicy foods etc) along with saline rinses twice daily. NONE OF THIS HAS HELPED. I have used FloNase and every allergy medicine available.

There is much much more to add, but I will do that in a separate post. Very frustrating, but I try to remain hopeful.
