The Common Cold

The common cold is a disease that is caused by an infection. Those affected by a cold will usually display symptoms such as a sore throat, runny nose, headache, and more importantly, sinus inflammation due to infection. Swelling in the sinuses closes the passageways, making it harder and harder to breathe. The common cold is typically self-treatable and can last for a week or up to 10 days.


The environment can severely affect people with allergies, especially in the nose. The cause of your symptoms can vary depending on what kind of allergies you have. People with seasonal allergies are most likely affected by pollen, while those who experience symptoms all year round are probably allergic to dust, pet dander, and other household allergens. Stuffy nose and trouble breathing are common symptoms that can happen several times a year.

Nasal Polyps

People over the age of 40 are very likely to develop growths in their nasal cavity. These are called nasal polyps. The bigger they are, the more of a problem they become. Without proper treatment, it can interrupt breathing, block nasal drainage, and has been known to affect the sense of smell and taste. Some physicians have even linked nasal polyps to allergies and asthma.

Deviated Septum

A deviated septum is a deformity of the nasal septum, caused by a natural occurrence or damage to the nose. The nasal septum part of the nose separates the two nasal passageways. If the nasal septum is asymmetrical, it blocks one of the passageways and breathing becomes difficult. A significant number of people (around 80 percent) have a deviated septum. These people are also more likely to suffer from a sinus infection as the blockage prevent bacteria from leaving the sinuses.

Taking care of a Sinus Infection

Aside from nasal polyps and a deviated septum, these conditions are easily treatable with balloon sinuplasty. Balloon sinuplasty is a safe, non-invasive procedure that resolves your sinus infection with minimal side effects. Your situation can grow worse if you don’t seek help soon. See a doctor about any of these conditions as soon as possible, and talk to an otolaryngologist about balloon sinuplasty as a viable treatment option.
