A sinus infection.
Sinusitis is an infection of the small, air filled cavities inside the cheekbones and forehead. Acute sinusitis is fairly common, with between one in five people in 100 being diagnosed with the condition every year. Acute sinusitis often develops quickly (over a few days) following a cold or influenza (flu). It often clears up on its own with little or no treatment. Chronic (persistent) sinusitis is less common, and can last for weeks or, sometimes, months.
If you have sinusitis, your sinuses become inflamed and swollen. There are two sinuses on your forehead (frontal sinuses), two are located at either side of the bridge of your nose (ethmoid sinuses), and there are also two behind your cheekbones (maxillary sinuses). It is the maxillary sinuses that are most commonly affected by sinusitis.
People of all ages can get sinusitis. Typical symptoms include a high temperature, pain and tenderness over the infected area, and a blocked or runny nose. Often, no treatment is required, but painkillers may be needed and, occasionally, antibiotics are prescribed.
It's a bacterial infection of the internal spaces behind your nose and eyes. You may have bad pain or nasty goo leaking out. Antibiotics will (hopefully) get rid of it within a day or two.
sinusitis sucks....its an infection of the sinuses that causes swelling, pain, pressure, drainage and is basically a big pain inthe you know what. They are common, I get several per year. Its almost as common as a cold these days. You should return to normal as long as you finish all the medication, even when you feel better, finish until they are gone.
according to my doctor it is what you get just before you get a sinus infection but yet they wouldn't put my daughter on antibotics. So depends on what doctor you get. Mine like to wait until you are in major pain so they can make more money on a second visit. Or atleast the one I saw because my doctor was out.
