I’m having a similar problem and I know it can really get frustrating, when my nose was dry I tried to saline nasal spray that helped a little, also saline can be couter productive because it’s salt. I later found a product called Nasacort without a prescription and this combined with a cold air vaporizer at night really worked. I got eye drops from the doctor for the itching and an antihistamine relieved the rest. I hope this helps you out or perhaps your doctor might have some better options for you, good luck.
