Any suggestions for never ending chronic cough?

Hey everyone! Before I go into everything, I just want to say in advance that I appreciate everyone who reads this and/or shares their opinion and tips. I greatly thank you!

Anyway to give some back story. I am 24 currently, but I’ve had asthma since I was a kid. I remember having a nebulizer when I was a kid as well, but I never really had major issues until I had walking pneumonia at the end of 2019. Since then, without fail, every two years I have had constant coughing moments. In 2021 it went on for a few months every day. However this time around, it has been going on for over a year since last year in 2023 in no end in sight. It feels like I just nonstop cough all day all night every day for the past year and a half. It keeps me up at night. I barely can breathe during the day, it’s worse at night as well.

I have been in and out of doctors. In this span, my allergist put me on nasacort, and my primary care doctor put me on pulmicort to breo ellipta to trelegy (which I don’t know why but half the time I barely can even inhale that thing to begin with without coughing lol, I have such a love-hate relationship with trelegy omg. if anyone has an easier alternative PLEASE TELL ME) + singulair at night. All three inhalers—none of have worked, so he recommended me to a pulmonologist, because he thought maybe it wasn’t my asthma that was causing the cough since the maintenance inhalers weren’t relieving it at all.

The pulmonologist the first time around did breathing tests and it was perfectly fine. So I did chest x-rays for my lungs and still everything was fine, nothing showed up. I did a sinus x-ray and he said apparently I have allergic sinusitis and a deviated septum, so he gave me an antibiotic (azithromycin) and put me on both azelastine nasal spray + xyzal.

To sum it up, at this point in time we’re at around april or so of this year in 2024. my regimen was trelegy + nasacort in the morning, and singulair, azelastine, and xyzal at night (and the antibiotics but those were short term).
Nothing really helped. I went back to my allergist to see if there was anything on that front I can do since my pulmonologist basically told me it was my allergies and sinuses that were the problem instead of my asthma. My allergist told me to stick with the nasacort but lose the azelastine and xyzal combo because it was unnecessary (which was fine because the azelastine gave me brain fog and for the xyzal I usually would traditionally take that only if my allergies got unbearable). He put me on another antibiotic (augmentin) to see if that would do anything. It didn’t help.

Let’s fast forward to the last few weeks. I went back to my primary care doctor recently basically as a plea at this point lol. He recommended an allergist. I went to see her a two days ago. She was very great. She was trying to figure it out. I was trying to follow her logic—clearly the inhalers aren’t working and she re-did breathing tests and they were again perfectly normal so she said it again may not be my asthma. she said though the nasacort is treating my seasonal allergies, it might not be getting deep enough because of my deviated septum, so she might want to put me on this nasal spray called xhance that apparently gets deeper into your sinus. however, she said the other possible condition that nobody has looked at yet that she wants to tackle first before prescribing that is GERD, which admittedly is an angle I have not thought about at all. She put me on omeprazole 40mg to reduce stomach acid, so we’ll see what happens. She told me to drop the singulair because she said it doesn’t do much. She is afraid to drop the trelegy just yet. Currently I am taking trelegy, nasacort, and omeprazole now. So far I feel the same, but it has only been a few days.

Either way, I know that was a long post and I apologize. It has just been really annoying. I just can’t sleep or breathe all day really. I just cough all the time, and at this point I have coughed so much that it almost feels like something is stuck in my throat where I catch myself having to clear my throat on top of coughing which sucks lol. Is it asthma, is it my sinuses, is it GERD, nobody really knows. It’s tough to have this constant cough and not know the cause of it and not know how to treat it.

Does anyone have any tips or anything? I know it’s tough to answer but any positivity you can give me would be awesome. Thank you very much!

And also side note, before I end here—Yes I forgot to mention I have a rescue inhaler and I have had other maintenance inhalers in the past and such. I just never really needed them long-term ever in my life until now, and what has been going on is just I don’t even know how to describe it. I have never experienced it like this before.
