Sinusitis and Sinus Infections

you have several sinus cavities in your head

Sinusitis is inflammation of the lining of the nasal sinuses that occurs as a result of an infection. These are the hollow cavities within your cheekbones around your eyes and behind your nose.


inflamed sinuses cause a lot of irritation

Sinusitis affects over 30 million Americans every year. Nearly half of the 30 million Americans that suffer from Sinusitis also have allergies. In many cases, an allergic reaction is the first step that leads to sinusitis.

Normally, mucus and fluids drain from your sinuses through tiny openings. Swelling that results from an allergy attack or an infection can block that drainage, resulting in a buildup of mucus in your sinuses. This buildup becomes a great spot for bacteria or viruses to multiply.


Sinusitis can be far more painful, and long lasting than a simple allergy attack.

If you're suffering from sinusitis, you likely have a pounding headache, pressure behind your eyes and cheeks, and mucous filled nasal drainage and post nasal drip. You may also lose your sense of taste and smell along with chronic nasal congestion.


Sinusitis treatment can vary depending on the type of Sinusitis that you have, and its cause. For example, if you have a bacterial infection, antibiotics may be a great solution. However, if you have a viral infection, antibiotics will not completely relieve your symptoms.

The table below shows the causes and symptoms of various types of sunisitis. For a better understand of how to treat each type of sinisutis, see the following pages.

Additional Problems Sinusitis Sufferers Experience

There are many other conditions tend to accomanpy Sinusitis. If you take steps to treat or prevent these as well, you are going to reduce your liklihood of developing sinusitis, or reduce the duration of your symptoms when they occur.

Post Nasal Drip: This frequently accompanies Sinusitis. This is the result of mucous running down your nasal passages and throat. You are likely to have throat and nasal irritation that accompanies your sinusitis symptoms. It will result in sniffling, as well as coughing up a lot of mucous and flem.

Hay Fever: Hay Fever (also known as seasonal allergies) is often a precurser to sinusitis. Anyone who suffers from hay fever is likely to develop sinusitis at some point in the future as the allergies block your sinuses and prevent healthy drainage.
