I recently ordered this  plastic device and it has provided me with
some  unexpected relief.  It inserts into the nostrils and pries them
open which makes it both easier to breathe fresh air over my  dry,
irritated tissue and also helps keep the tissue from chafing against
other membrane.  If I could wear it all the time I would but can only
wear it at home...I am planning to try something called a Nasal
Brace.  Any similar experiences out there?  Judy
