I have had an ongoing battle with nasal stuffiness for quite sometime. The left side of my face is numb (due to A.D.) so the left nostril and left eye have no moisture. I have had a plug put in my eye, taken out and then a permanent plug put in .For my nose, My ENT Doc. recommended that I use an All Natural Saline Solution. The one I use is called Sinu Cleanse. I imagine there are a dozen others. You will need a syringe to flush with. Mine comes in little packets to dissolve in water. This has helped me, maybe its worth a try.
