Do you know what is causing it? It may be diet or allergy related for instance. Mine is allergy related and I use four options. The first is Sterimar which is a saline nasal spray. I add in Beconase nasal spray to decongest if needed. If I have got face pain and headache with it, then I take an oral decongestant/painkiller mix instead of the Beconase and if its hay fever with itchy running eyes as well then I use an antihistamine tablet instead of the decongestant/painkiller.
