I have suffered from eustachin pain in my neck for years, and this was the first year it started to become daily, on both sides, and unbearable quite frankly.  This is the first medicine to ever relieve that pain, and completely.  i can only use 1 spray in both nostrils, more makes my heart race, but using it as i need allows me to use it not even daily once under control.  JUST AMAZING.  i do have minor allergies, just sneezing and it has stopped that as well.  a nice side benefit.
