Sorry I don't have any advice. But I wanted to say I hope you feel better soon. I am suffering with a cold and that is bad enough without being able to take anything.
Advice I do have is try to avoid dairy and caffeine, as these both stimulate mucus production which makes it worse. The last few times I have had an upper respitory infection, I have done this and it cleared up on it's own a lot quicker than it ever had done before.
I also find if I have a hot drink like hot squash or something, hold the warm mug against your chest (I do it between the boobs) and this helps ease some discomfort/pain.
I hope some of this helps x
