Just to let you know OTC nasal sprays make it worse if used for more than the recommended dose. It's called rebound effect. My mother was addicted to them and hard to get off since nose is always plugged up. See your doctor or an ENT, you may have a deviated septum or just chronic inflammation. They can prescibe a steroid nasal spray to reduce the swelling.
I agree with asking your doctor about allergies. Do you live in a city? Hot summers make the pollution levels in the air go sky high. Also, if you live in the country near a field pollen and dust from the fields can make you very stuffy. I had that problem growing up in Ohio.
I also had a friend who had polyps on her sinuses that made her nose stuffy 24/7. She had to have them removed to clear her nasal passge out.
Nasal sprays are only a temporary solution. Like the previous poster said, eventually they stop working and can make things worse. See your doc.
You might check for food allergies if you haven't. Common ones are dairy, wheat, corn, soy, gluten, citrus (orange juice is especially bad), and anything processed and refined. Sugar and high-fructose corn syrup also.
Drink lots of water - room-temperature or chilled, but no ice. About half a gallon a day or more if you need it.
oh i was having alot of problems with stuffy nose and swollen eyes. I was taking claritin, then allegra and it did nothing. FInally the allergist gave me a spray for the nose, nasocort nose spray and changed my tablets to singulair 10 mgs, and it has worked wonders!! i couldnt believe it. one tablet at night and i can sleep without a stuffy nose and can wake up the same. He made a face when i told him i was taking allegra as in it wasnt up to par i guess. hope it lasts. alot of these things work fine for a few weeks, then stop working.
