(Concern) Do you have any tips or secret methods for treating rhinitis in the ENT department?

My hay fever has come back recently. It was okay for a while, but maybe because the weather got hotter, I’ve been exposed to a lot of air conditioner and fan breeze, and now clear nasal discharge is flowing again. It’s uncomfortable to blow my nose, and just leaving it alone is still uncomfortable. The medication prescribed at the ENT clinic seems to be only temporary. I also received a prescription for a nasal spray, but that also seems to be temporary. I want to avoid surgery, but do hay fever sufferers have any personal tips or secret remedies?
