I have had a persistent dry cough for 3 months now, and phlegm - its not all the time mostly during night time.
When I was younger I had asthmatic rash, but I have never had a problem with hayfever. I am allergic to dust though, I seem to break out in a rash
My doctor says I have rhinitis, i've taken Zyrtec, antibiotics, phlegm dissolvers and I still ahve this cough.
Any idea what it is?
