Your sinuses are chambers in your skull around your nose and eyes. They are filled with air. Sinusitis is an infection of these chambers, which causes them to become swollen or inflamed.
Many cases of sinusitis clear up on their own. Most of the time, you do not need antibiotics if your sinusitis lasts for less than 2 weeks. Even when you do use antibiotics, they may only slightly reduce the time you are sick.
Your health care provider is more likely to prescribe antibiotics if your sinusitis lasts longer than 2 weeks or recurs often.
Your provider may also refer you to an ear, nose, and throat doctor or an allergy specialist.
Keeping mucus thin will help it drain from your sinuses and relieve your symptoms. Drinking plenty of clear fluids is one way to do this. You can also:
Use a humidifier to keep the air in your room moist.
You can buy nasal sprays that relieve stuffiness or congestion without a prescription. They may help at first, but using them for more than 3 to 5 days can cause your symptoms to get worse.
