Place that specializes in effective rhinitis treatment

I have quite severe rhinitis, and as I get older, my symptoms are getting worse.

Sometimes, when I eat spicy or hot foods, I get a runny nose, but I just get a runny nose when I eat.

I think it's also impolite to blow your nose while eating with others, and I can't really eat while running a runny nose... Since I also have a runny nose, I keep getting distractedㅠㅠ

Please recommend a good place for rhinitis treatment^^
