Things to try:
http://tiphero.com/5-simple-home-remedies-for-your-stuffy-nose/I get a stuffy nose quite often in the cooler/cold months, but I'm not sure if it's an allergic reaction, sinus-related, or something to do with my fibro, each time. These remedies may be worth trying, but I would caution that some people could have an allergic reaction to the ginger. Personally, though, I love ginger tea!
