Is Sinusitis caused by allergy? 

Allergy is often something that goes hand in hand with allergy but is rarely to true cause of sinusitis in and of itself.  As most chronic sinusitis is a disease of inflammation or swelling, and additional cause of swelling (i.e. allergy or viral infections) makes the situation worse.  Allergy symptoms are often misdiagnosed as sinusitis and sinusitis is misdiagnosed and treated as allergy.  An allergy evaluation is critical in sinusitis management for these reasons.
