What role do allergies play in sinusitis?
Many patients with chronic sinusitis have allergies which may partially complicate sinusitis. Allergies cause swelling and blockage of the tiny holes which allow drainage of mucus from the sinuses. In addition, the allergies may cause swelling inside the sinuses and inside the nose. It is critical that patients with allergies control their environment in order to control their sinusitis. Because so many patients with sinusitis have allergies, we have included a section on allergies later in this website as well.
