And I have rhinitis. I have been to many hospitals.

But personally, I don't think it is particularly serious. I saw it once in Shangrao Railway Hospital, and I felt quite good! Recommend it!

But I personally have nasal polyps and sinusitis (not very serious), because there is no systematic treatment for other reasons!

If it is local, go to the railway hospital.

I hope your father will recover soon.

-P.S. When I was young, my mother also had rhinitis. Later, she took Chinese medicine and ate well. I don't know anything about medicine. Please ask my Chinese medicine friends. ) I just eat round plants that stick to other people's sweaters. I used to play when I was a child!
