When I caught a cold and had a sinus infection, my aunt would apply a drop of sesame oil in each nostril and then do a little circular message on the the tip of my nose. It was so great, it relieved me a lot. If she couldn't finds sesame oil, then she used some menthol or vapor rub and it worked the same. It's a simple thing you can do but it's very beneficial. She actually always wanted to use a drop of onion juice instead of oil but I never let her because I couldn't stand the smell of onions. But I'm sure that works just fine too, if you're looking for some sinus home remedies.
