Hi
I hope you feel better by now. it sounds as if it might be pertussis especially if you never had such cough before and when you don't cough, you feel good (i.e. no fever or other flu symptoms etc.).
I can offer you to listen to your cough by recording it, better more than once, in different times. you can send it over any format. i can try to diagnose since the sound can be a great help for such diagnosis.
Take care and be well!

I had a bad cough for a solid month. Mostly at night when it felt like someone was tickling inside my throat w/a feather. I didn't have any congestion or fatigue with it.
Now for 3 days my husband has had the same bad cough but he had a temp of 100 last night and he's quite weak & sweaty. But then, he's diabetic.
Best thing I did for mine was to suck on honey lemon cough drops all night. Now I can't stand the sight of those drops.
what could it possibly be, assuming it was from the upper or lower airway, anything fatal?
It is not uncommon to have a prolonged airway hypersensitivity following an upper respiratory tract infection. This may also cause you to wake up during the night or early morning coughing. Another possible cause of this type of response is that the sinuses have become involved due to your infection. Inflammation and/or infection of the sinuses can cause the same type of coughing response. Since this has been going on so long and not responding, it is a good idea to speak with your doctor. Then it can be determined if this cough is coming from the upper or lower airways and treated appropriately.
