Sinus infection, or sinusitis, is an inflammation of the sinuses and nasal passages. A sinus infection can cause a headache or pressure in the eyes, nose, cheek area, or on one side of the head.
Sinusitis from a bacterial infection might cause pain longer than the week of a typical cold. Your doctor may give you antibiotics and other medications to help you feel better. Whether your sinus pain is caused by a cold or a bacterial infection, here's how you can relieve it: Use a saline nose spray. Ask your doctor or pharmacist to suggest a plain saline spray. Saline mist will ease sinus swelling and help break up the mucus that's clogging your nose. You can use it up to six times a day without worrying about side effects. You can also make your own saline nasal spray.
