Welcome to the forum, muffincakes.
As Sherry advised, your ENT can look inside the nose and advise you.
For a little relief in the meantime, have you tried a saline spray? I prefer the pressurized ones with only saline, no additives. I also get relief from dry nostrils from Ayr gel, which I use at night when I'm in a dry environment, like now that the house heat is on. Don't use petroleum jelly, only water soluble products.
