Many of the symptoms of a sinus infection are the same you’d experience with a bad cold. They include: postnasal drip (that thick mucus in the back of your throat), discolored nasal discharge (green mucous coming out of your nose), stuffy nose or nasal congestion and tenderness or pain in the face – usually under the eyes or around the nose. You can also have headaches, tooth pain, coughing from the post nasal drip, fever, fatigue, a bad smell in your nose or a bad taste in your mouth and bad breath. Symptoms such as a fever that won’t go away, a change in your eyesight, severe headaches and neck stiffness need immediate medical attention.
The goal of sinus surgery whether it is performed endoscopically or via balloon sinuplasty is to make the small drainage openings of the sinuses into the nose larger. That's it! By making the sinus openings big enough, the sinuses can't get obstructed as easily and therefore allow for good sinus drainage no matter how much swelling or inflammation may be present. Good sinus drainage prevents/minimizes sinus infections. Paradoxically however, sinus surgery may make your allergy symptoms worse (easier for allergens to gain access into your nose and sinuses since things are opened up), so it's very important to get your allergies under good control before sinus surgery is performed. For those with asthma, having sinus surgery has been shown to markedly improve lung function resulting in decreased number of asthma attacks and use of inhalers overall.
