Sinusitis is an inflammation of the mucous membrane that lines the sinus cavities (located around the nose). What causes it? An infection (resulting from a common cold, tooth abscess, or other ailment), allergies such as hay fever, or an injury to the nose. Once someone has the sinus disorder, it may go away only to return the next time a cold hits.
Unlike conventional medicine, many alternative therapies believe that the symptoms and infectious organisms related to sinusitis are not the primary concern. Instead, these treatments try to uncover the causes of the sinus disorder.
