BEST REMEDY: APPLE CIDER VINEGAR
Organic Apple Cider Vinegar is our favorite remedy for stopping sinus infections. We wish more people knew about this amazing home treatment. The idea is to take apple cider vinegar before the sinus infection occurs, which for most people is at the start of allergies, colds, flu, etc.

There are a couple ways you can drink apple cider vinegar ("ACV"). One way is to put 1/8 to 1/4 cup ACV in 16 oz of water and sip it throughout the day. The other method is to gulp 2 TBSP of ACV in 8 oz of water all at once.

If you have an existing sinus infection, keep drinking a mixture of ACV and water throughout the day for several days.

Yes what pamela said is very good there is another way for instant relieve is put your head over a basin full of hot water with albus oil  a few drops and put atowel over your head and inhale for a about 15mins you will be able to breath and it clears the sinuses and instance reliefe

Saline solution is good for washing the gunk out but, you still need antibiotics to stop the infections from traveling (like to your teeth! ouch!)
