Nasal irrigation nose sweeper for severe rhinitis

I have had severe rhinitis since I was young.
Whenever the cold wind blows, my runny nose flows like a stream, and the medicine doesn't work well..
It was really hard. I also heard that it's okay to have my nose rinsed at the hospital.
I purchased and used it. My nose feels very uncomfortable and dirty because of the runny nose.
It feels refreshing after cleaning. At first, I was confused because I didn't know the method, but now I do it well. It's not like it completely cures my rhinitis, but I think it provides some help.
