Apart from the usual medicines, I use heat and moisture for dealing with my dicky snozzle (and the migraines it triggers).
At first sign, a pan of water on a low light is usually my first step (doing the dishes with scalding-hot water should let you know if it [steaminess] is a goer for you); above 75% humidity is the key (I spend my waking hours in the kitchen, so it's easier for me). You may need to keep the temperature up in whichever room you do it (the kitchen, I'm guessing) to stop the moisture condensing on everything.
I also use a heatlamp for both the onset of problems and the following migraine (when I awake with a migraine, it's pan on, heatlamp on, absorb for half an hour and see if I'm upto the motion of taking a tablet).
Sometimes, I'll stick my nose over the toaster and suck in the heat until it stings (the rapid drying seems to trigger a response and the heat should kill germs).
I also use a heatpack, with an antibacterial wipe, for applying heat and disinfectant to my scalp (sometimes, an infected scalp-pore can trigger an over-reaction, since there are relatively few nerves there, but a good blood supply).
I've found that cleaning out my nose with the aforementioned wipes helps avoid problems getting worse, especially if problems are caused by pollen and pollution. I don't know if that's desensitization or what...still toying with it.
And then, there's Dolly......
Her, I Will Always Love You, reduces me to tears because I envision it as the moment of a mother and child separation with both telling their parts for their choice.
Oh, look: you made get teary-eyed just thinking about it and of how to word it šš¤§š¤š
There's bound to be a song that does it for you....or watch My Dog Skip.
