What is rhinitis?
Rhinitis is an inflammation of the mucous membranes of the nose with symptoms of sneezing, itching, nasal discharge and congestion. It can be allergic, nonallergic or both. Season allergic rhinitis is caused by substances that trigger allergies, called allergens and is sometimes referred to as hay fever. Perennial allergic rhinitis is an IgE-mediated reaction to allergens that show little or no seasonal variation. It is persistent, chronic and generally less severe than seasonal allergic rhinitis.
What is sinusitis?
Sinusitis is an acute (very intense) or chronic (happening repeatedly all the time) inflammation of the nasal sinuses, the hollow cavities around the cheek bones found around the eyes and behind the nose. Sinusitis, which is common in winter, may last for months or years if inadequately treated. Sinusitis can affect the nose, eyes, or middle ear, and may be indicated by plentiful, thick, colored nasal drainage, bad-tasting post nasal drip, cough, head congestion and an accompanying headache. Symptoms may also include a plugged-up nose, a feeling of facial swelling, toothache, constant tiredness, and occasionally, a fever.
