I had a bad cold about three weeks ago, and I seemed to get over it. I don't take any medication just Manuka Honey and fresh orange juice.

Since then, I have been waking up with the back of my nose and throat so dry, my mouth also, feels tacky and I have been feeling unwell.  I have this come and go throughout the day, but mostly in the morning.  I feel nauseas and my head feels full and I also have ringing in my ears.  The back of my nose feels blocked, but I don't have any mucous running into my throat or from my nose.  I have looked up Sinisitus but I cant seem to identify the same symptoms. Can anyone give me an idea.  I will soon have to go to the GP but all I will be given is a nose spray, which I know you cant use after 7 days.  I need to know really if there is any other solution first.
