Vindaloo.
Or go to your local Chinese shop and ask for “Bak fah yeow” (white flower oil) and sprinkle that up your schnozz.
Also, I went on a sunbed once with a veddy blocked dose, and within minutes I could breathe again completely. (I also once had a massive adrenaline rush during an asthma attack and that cleared that up too.)
find an indian restaurant. order the vindaloo, and tell em to make it india hot.
seriously though, i remember recently reading that the brits did a study that showed people who ate indian food had less problems with colds. I just can’t seem to find the article right now.
I learned to love the Neti pot right here on the dope. Once a year I get a stuffed up nose that I cannot even forcefully blow through. Complete air tight blockage from the swelling. Miserable. Unable to sleep, the next tired day becomes a grumpy, stuffy blah experience.
What works for me is eating a whole jar of sliced jalapeno peppers. I will sit down and eat the entire jar by itself. It works fabulously well when followed by the Neti pot and fifteen minutes of leaning over the sink blowing that crap of my head. It is amazing how much gunk comes out.
Jalapenos work. You will regret it the next time you go to the bathroom, but it is worth the trade off.
I don’t know if Sam is around but to help target the advice please note that she is in the UK so some medications may not be available, but those which are will not be excruciatingly expensive.
That said, spicy food always does it for me, at least temporarily. Even an extra hot Nando’s or something with a healthy dollop of wasabe or English mustard will get the nose going. (Wasabe and English mustard will also hurt like hell but if you’re going to be a wimp about it stop whining about your nose.)
Conversely I always find that washing out my sinuses with water by any method always results in a proper sinus infection. My sinuses are perverse.
Although this is a few days late, since it hasn’t been mentioned and for the purpose of anyone who may read this later, I must recommend vicks inhalers ( http://www.amazon.com/Vicks-Inhaler-007-oz/dp/B000052X7B ). The active ingredient is levomethamphetamine, or as they call it, levometafetamine (or something like that). Its the inactive “cousin” of methamphetamine, more or less, in that it does not cross to the brain and provide any sort of high (CNS stimulation), only in the body, unclogging your nose and possibly providing a little bit of jitteryness (PNS stimulation). All I have to say is that it works incredibly well for unclogging stuffed noses, ones stuffed for a variety of reasons, and works fast. And no, I don’t care if you get it from that site, I just wanted to provide a link to show the product. Its not great for long term for use, say using multiple times a day for several days straight. but for short term use, or every so often, nothing is better in my personal and professional opinion.
Sorry for not posting earlier to say thanks for all the suggestions - thanks, anyway. 
I’ve now tried all of them except the medications which aren’t available here, and the sunbed, which I will probably try soon. The neti pot was very disappointing - the water just stayed in the pot, not going into the nose at all. Guess it’s too locked.
Last night I ordered a pizza over the phone from a Turkish restaurant. Mean waiter refused to understand what ‘hubbus’ was even though you’d think the context of a Turkish restaurant would make it fairly obvious what I meant, so I ended up going without. 
(He was a native English speaker).
Think I might have to actually got to the doctor. For some of my work having a clear speaking voice is essential, so this is actually doing me out of rather a lot of money.
Olbas Oil is quite good and def. available.
I know you said you weren’t going to the doctor, but may I ask why? If my nose was clogged for over two months, I’d be a little worried. That doesn’t sound normal…
Actually, in post 26, he says he is going to give in and go to the doctor.
Ack, sorry. That is what I get for skimming.
She.
Ah. Thanks. Sometimes it’s hard to be sure!
It’s a very mild complaint, not the sort that I’d usually consider worthy of a doctor’s visit. I feel like a hypochondriac.
Wow, that must be one real stuffed-up nose then 
Nah, I don’t blame my sinuses (although this morning for some reason, they are set on “Full-On Homicide” mode. . .)
In the norinew household, everything that is wrong in the world can either be blamed on the cats or The Spice Girls.
