An allergy is a reaction by your immune system to something that does not bother most other people. In most instances your immune system fights germs; it’s your body’s defense mechanism. However in an allergic reaction is your body responding to a false alarm.

Allergies are commonly misdiagnosed as sinusitis or sinus infection. It can be tricky to know what condition you have, even for your general physician. Los Angeles allergy doctor and sinus expert Dr. Farhad Sigari can help.

Nasal Obstruction

By definition a nasal obstruction is anything that impedes the flow of air into and out of the nose and may block one or both of the nasal passages. Think of it like that really bad cold where you can’t breath through your nose. The nasal passage is very important to breathing. About 70% of airflow to the lungs is from nasal breathing, so if your nasal passages are blocked, you may have trouble breathing and sleeping. Learn more about these conditions, like a deviated septum, enlarged turbinates, and nasal polyps and how we can set your nasal passages free.

Sinus Headache

When your sinuses are inflamed, through allergy, bacteria or other causes, the area of your sinuses, inside your forehead, cheekbones and behind the bridge of your nose produces excessive mucus. The channels and pathways that normally  drain the mucus can become blocked. This leads to that build-up of pressure that feels like a headache, but can be much more painful. We can help.


sinusitis like all medical terms ending in “itis” is simply an inflammation or swelling of the tissues, in this case in the sinus cavity. There are two kinds of sinusitis, acute (or acute bacterial) and chronic, which are similar in some but not all aspects. Learn if are experiencing symptoms that maybe acute or chronic.
