I have nose allergy.my nose remains extremely dry.it gets better in humid environment. when i wake up there is layer of mucus coating inside nose.help?

Some Suggestions: Since you know you have allergies, take an antihistamine like claritn or zyrtec (or their generics- available over the counter).You may also wish to try some of the saline nasal sprays to help hydrate the area - especially before going to bed or even try using a humidifier when you sleep. This spring allergy season is worse than typical for a variety of reasons.
