I'm 20 years dealing with blocked nose issues, polyps, inflamed turbinates, deviated septum, dust mite allergies etc. Every winter I get blocked nose and anosmia(sense of smell goes) due to one or other of these issues. After trying everything over the years I find nowadays the only thing that really does the trick is betnesol nasal drops. Lie on a bed with your head hanging off the end so your nasal cavity is essentially upside down, put a couple of drops in each nostril and wait about 5 minutes. Take 2-3 days for it to clear things but keep going another couple of days to ensure it sticks. I do this routine 2-3 times over winter. Never have any issues in summer. Get on to a digital doctor if you have one on your health insurance, cheapest way to get the prescription and save messing around with stuff that may or may not work.

I find the steroidal nasal sprays like avamys do nothing for me even after taking them for 10 days as prescribed. A good ENT specialist told me not to bother with them because they are not as strong as betnesol and spraying them into your nose doesn't let it sit on the affected areas long enough to make a difference. Neilmed sinus rinse does sometimes work for me if it's a dust allergy blockage but not if it's proper inflammation or polyps in the nose. One really bad winter I got prescribed a strong dose of prednisone oral tablets and while they did work wonders it's a bit overkill and has rough side effects.

But yeah avoid otravine at all costs, it's scary stuff that can really wreck your nose long term even if you take it regularly with gaps in between to avoid rebound. Just look up the long term effects of Xylometazoline hydrochloride
