allergic rhinitis
"For many many years I have been dealing with hay fever allergies in spring and fall.  My nose is always clogged.  Sudafed and Allegra D became a normal routine for me.  Dr gave me a trial of this.  Loved it, the only side affect was that I could breath through my nose which is not normal for me in my life.  I actually felt more active but may be just a side affect from being able to breath through my nose.  They only get 9 of 10 because it is expensive, $180 without insurance, $80 with coupon card.  Insurance is fighting me with pre-authorization."
