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.
There’s type 1 and 2 diabetes. I believe type 2 requires you to regularly prick your fingers to test your blood sugar levels several times a day while type 1 requires mandatory insulin shots into your stomach a few times a day. Basically a diabetic fuckin hates needles for good reason and to be able to do that with ultrasound would be rad.
