I have a non-steroid nasal inhaler called petanase. http://www.patanase.com/
I am not sure if this is what you're looking for. Unfortunately, it is a drug.
I thought i had allergies but now I am thinking I have sinusitis. I saw an allergist and it shed no light on my situation. I am seeing an ENT soon. I hope I can get an answer about
why my sinuses are so clogged up. Especially late at night, if I wake in the night and in the morning, I can't breathe at all. It makes it difficult to sleep.
