My rhinitis is getting worse.

Originally, I didn't have severe rhinitis, but this time my nose suddenly became blocked, I have a runny nose, and I keep sneezing as if I have a cold.

It seems to be allergic rhinitis, but it doesn't get better even after taking medication. If medication doesn't work, what should I do to resolve it?

Is time the only cure? Or should I go to another hospital? It seems like all the nasal allergy medications are the same.

Does anyone know of another method?
