Occasional nasal congestion and sneezing!! Could it be allergic rhinitis?

Sneezing repeatedly without any reason each time.

I sometimes have a runny nose. It's not severe, but it happens periodically.

I think it might be allergies rather than allergic rhinitis because it seems repetitive.

I want to receive medical treatment at the hospital. How is the treatment done?

I'm curious, how are people suffering from rhinitis managing their condition?
