Lie down on your side with the clogged nostril higher than your clear nostril. Breathe normally and you’ll notice your nostril will unclog after a few minutes, works 90% of the time.

Think of the clog as a mass behind your nose and gravity is shifting it to the middle. FYI it might switch to the other nostril, so it might take a few attempts before you clear both and at the very least you get a bit of easy relief without meds or more aggressive methods.

1. Do the maneuver @Dadbod89@lemmy.world suggested.

2. Try Flonase. Helps a lot but takes 1-2 weeks to start to work.

3. See a doc if things persist.

Do not listen to medical advise on a public forum. Most advice will not help and some may actually be harmful.

Ask a doctor or at least pharmacist.

My current understanding (as an engineer not a medical person) is that the human body shrinks one nose side itentionally. This way you have a wide nose way and a narrow one. This leads to different airspeed which lets you smell different stuff better. The body changes sides in intervals. One allergic reaction is that the interior of the nose swells more. So the narrow path will become even narrower until it blocks.

There are substances that combat this swelling, but using them for too long can severely damage your sense of smell and health.

When I got COVID and my sinuses were welded shut, I ate some Ghost peppers and it was like suddenly opening the valve on a firehose.

Go to a chemist and get some pseudoephedrine. That stuff is magic for blocked noses.

Wait isn’t that normal? I’ve only have like 1 functioning nostril for a while. Maybe thats why I feel like I’m always out of breath.

I had a septoplasty and inferior turbinoplasty many years ago, and had to rinse my sinuses every few hours to keep the wounds clean. I’d recommend Flonase sinus rinse, as some others in this thread have. The kits are pretty cheap, and the salt mix they provide is dosed so it’s much less harsh than table salt and won’t irritate or dry out mucous membranes in your nose. Using table salt for this purpose like some others are suggesting here is madness! Even before my surgery it hurt like hell, trying that.

I’d also recommend talking to an Ear/Nose/Throat specialist in case there’s something wrong that can be corrected, like enlarged turbinates. That was my issue - blood was pooling in the tissue when I lay on my side due to gravity and low blood pressure - hence the turbinoplasty. It was better for a bit, but did come back over time; dunno if this is normal, if they grew back, if the surgery didn’t work, or if the doctor was just wrong 🤷

I had issues with my nose for ages and got the tip to use a Rhino Horn from a friend. Using it daily helps a lot, but still one passage gets clogged up regularly. This is a cheap way to clear the passages, as all you need is water and kitchen salt. (later I discovered I have hay fever… ah well, this works better then any medication.

Flonase helps me tremendously when ragweed season hits.

I don’t know why this works or if it will work for you, but it works for me like 95% of the time when I have a mild cold or something. Breathe through your nose as slow as you possibly can. That’s it. Obviously don’t pass out so if you feel you have to, then take a few normal breaths. It helps if you’re calm and your heart rate slows down.

I used to get addicted to nasal sprays all the time and haven’t used one since I found this method.

1. Steaming hot shower, get your face warmed up, and try and blow your nose and clear it up as much as possible.

2. Grab a bowl of hot water with salt to make a saline solution (cool enough to dip your fingers in though) should be a bit saltier than tears but not more than that. Pour a bit into your hand and snort it in small amounts at a time, this may be hard at first but easier once you get the method down. You should start to taste the salt water in the back of your mouth. Do this a few times in each nostril, and finish off with fresh water if you can’t stand the taste, but try let the saline in as much as possible. Towel dry, and give it a minute or two, then blow your nose. Repeat if necessary. After 10 Min your nose should clear right up as the salt will help break all the mucous up.

Do this periodically or seize the moment when your nose momentarily clears enough.

I don’t know if this could help even with allergies but I usually do this https://piped.kavin.rocks/watch?v=I47xi2F3W9g and it’s awesome
