Yeah, that's what I learnt from the article I found.Allergic rhinitis is just a broad term that covers hay fever and other symptoms of upper airway symptoms that you have - there can be many, many precipitant.
Before going to bed last night, I took the only thing I had at home for a runny/stuffy nose, i.e. Panadol Cold & Flu, which contains pseudoepherine hydrocloride 30mg and chlropheniramine maleate 2mg (besides the paracetamol). I don't know if it worked, but I'm sneezing less today, and the nose has become less runny/drippy. (Didn't take any medicine today).Try taking some anti-histamine like clarytyne or telfast and see if it works.
