Rhinitis

I am in upper elementary school and have had a runny nose since I was young, which often caused nosebleeds.

I thought it would be okay when I got a bit older, but it seems to happen more often these days, especially during dry seasons.

When I was young, I had frequent nosebleeds, and when I went to the hospital, they only told me that my nasal mucosa was dry and cracked.

There doesn't seem to be any special treatment.

How do you manage children's rhinitis?
