Hi , previously i had severe allergy rhinitis, which I treated with homeopathy. Was ok for some time, then started developing sinusitis symptoms. Now sometimes I get this mixed attacks, itchy nose , sneezing, and severe nasal congestion. Nose is completely blocked even after using nasal sprays repeatedly. It's like i just can't breathe through my nose. Even when I don't feel like getting allergy, my nose is always blocked, I have to use spray continuously through out the day, every day. I have taken cetzine, sneezing is less now, but nose is blocked, spray is also not working. What treatment should i go for ? Can I take montair lc now? Unable to breathe, please help.
