Ayr makes something that can help with this. It is called Ayr Saline Nasal Gel, mfd by B.F. Ascher & Company. It has a little bit of a menthol smell to it. The directions are just to apply it around the nostrils and under the nose. It may also be used inside of the nostrils to relive discomfort from allergies and dryness, as well as to moisturize. It also helps prevent drying and crusting. It is a great product, and can usually be found right in the same aisle as the saline nasal sprays. Saline nasal sprays are also very helpful.
If you don't want to buy the gel, then vaseline is also very very good to relieve dryness. But this products also helps relieve itching and discomfort as well. Hope you feel better soon.
