Flushing with a syringe means that salt water will pass through the nasopharynx into the throat, so it should not hit the brain)))). Dalphin is sold in pharmacies, there is a special bottle for flushing, where water should not go down the throat, but pour out of the other nostril, detailed instructions are attached.
The pharmacy sells spray cans for rinsing the nose with instructions on how to do it. Better to use them than a syringe. The instructions say - flushing the right nostril, tilt your head strongly to the right, left, respectively to the left. When you rinse with such a spray, it doesn't hurt the brain. I bought Aqualor, it is convenient, it helps.
It depends on what you wash. I only rinsed with brine. There seemed to be nothing hitting the brain, only the solution passed into the throat. This meant that I washed my nose well.
If I simply can’t eat almost everything that you eat, I’m just disgusted with most of the food, and what can replace tasty, affordable, various chips, fast food, sweets, I don’t know, because it’s delicious, high in calories, and not disgusting ..
