I have had what feels like pre-cold for over a week. It has not got worse or better, i don't understand. This is what's happening, i feel some nasal congestion in the back of my nose and like dryness when i wake up. This will feel better as the day goes on and after clearing out some mucus but then it's all back the next day. It feels like a cold but it has not changed in over a week. Usually if I'm sick, there is a progression and change of symptoms. It will get worse, peak and then go away. What ever this is it just stays the same, well it goes away after a while when I'm awake but after sleeping it is right back where it was the day before.
