<p><strong>What Is Sinusitis?</strong></p>
<p>Sinusitis is an inflammation, usually due to infection, of one or more of the four sets of sinus cavities within each side of the facial skeleton. When irritated, the mucous membrane lining the sinus may swell and block the small drainage channels that permit mucus to flow into the nose. The buildup in pressure often results in headache, nasal congestion, drainage and facial pain. Acute sinusitis is a common disorder that often follows a cold or flu; chronic sinusitis refers to persistent or recurrent episodes that are generally milder than acute cases. Sinusitis often subsides on its own and responds well to home treatment. Rarely, infection may spread to the eyes or brain, possibly leading to vision loss, meningitis, or brain abscess.</p>

Complications Bacterial sinusitis is nearly always harmless (although uncomfortable and sometimes even very painful). If an episode becomes severe, antibiotics generally eliminate further problems. In rare cases, however, sinusitis can be very serious. Osteomyelitis. Adolescent males with acute frontal sinusitis are at particular risk for severe problems. One important complication is infection of the bones (osteomyelitis) of the forehead and other facial bones. In such cases, the patient usually experiences headache, fever, and a soft swelling over the bone known as Pott's puffy tumor. Infection of the Eye Socket. Infection of the eye socket, or orbital infection, which causes swelling and subsequent drooping of the eyelid, is a rare but serious complication of ethmoid sinusitis. In these cases, the patient loses movement in the eye, and pressure on the optic nerve can lead to vision loss, which is sometimes permanent. Fever and severe illness are usually present. Blood Clot. Blood clots...
Did you ever wonder why one person develops chronic pain following an injury, while someone else with a similar injury fully recovers and has no pain? Researchers at Northwestern University wondered so they set out to discover an answer. Their findings were published online July 1 by Nature Neuroscience .
The first longitudinal brain imaging study to track participants with a new back injury found that the chronic pain is all in their heads––quite literally.
No, they're not saying the pain is psychological. What the new Northwestern Medicine study shows for the first time is that the more two sections of the brain––related to emotional and motivational behavior––talk to each other, the more likely that chronic pain will develop. The more they communicate following the initial injury, the greater the chance a patient will develop chronic pain.
Study Design and Results
A total of 40 participants who had an episode of back pa...
