There are various causes for these symptoms, although they are broadly divided into two types: allergic rhinitis (nasal symptoms related to allergy) and non-allergic rhinitis (nasal symptoms that are not related to allergy).
Symptoms of rhinitis may include:
Rhinitis may occur before a case of sinusitis or with sinusitis, a condition where infection or inflammation affects the sinuses. If you have facial pressure, decreased sense of smell, or a greenish-yellow nasal drainage, you may also have sinusitis. A qualified ENT (ear, nose, and throat) specialist, or otolaryngologist, can provide a thorough evaluation and appropriate treatment for your nasal/sinus condition.
Allergic rhinitis occurs when your body’s immune system over-responds to specific, non-infectious particles such as plant pollens, molds, dust mites, animal proteins, chemicals, foods, medicines, insect venom, and other triggers. During an allergic attack, a special antibody (fighting protein), called IgE, attaches to cells that release histamine and other chemicals in the lungs, skin, and the mucous linings of the body. These chemicals open the blood vessels and produce skin redness and swollen membranes. When this happens in the nose, sneezing, itching, runny nose, and congestion occur.
Seasonal allergic rhinitis depends on specific plants that are pollenating at that time. In the United States, springtime allergic rhinitis is typically due to pollinating trees. Early summer allergic rhinitis is often due to grass pollination, and allergic rhinitis in the fall is usually due to weeds pollinating. Hypersensitivity to ragweed is very common in autumn. Also in the fall, you may experience allergic symptoms from mold spores on falling leaves.
Perennial allergic rhinitis can be felt year-round and can result from sensitivity to animal proteins, mold, houseplants, and dust mites in carpeting and upholstery. When seeking a medical evaluation for suspected allergic rhinitis, it is important to be aware of the pattern of symptoms (seasonal triggers, indoor vs. outdoor, specific triggers, animal exposure, etc.).
Non-allergic rhinitis and vasomotor rhinitis (a type of non-allergic rhinitis) do not depend on the presence of IgE antibodies, and is not due to an allergic reaction. You can have non-allergic rhinitis even if you test positive for allergies. Some of the causes of non-allergic rhinitis include:
Are There Related Factors and Conditions?
Depending on the type of rhinitis, certain conditions may be associated, such as:
Treating rhinitis depends on the specific cause or diagnosis. If there is a specific trigger that can be avoided, this may be a successful treatment. For example, in people with cat allergy, avoidance of cat exposure and direct contact with cats may help to control symptoms.
Often, medications are used to control symptoms. Depending on the specific cause of the rhinitis symptoms, some of the medications that may be used include:
For allergic rhinitis, allergen immunotherapy may be an option. This is most commonly provided via allergy shots or tablets or liquid drops taken under the tongue. Again, a qualified ENT specialist or allergist should assess your situation to determine whether allergen immunotherapy is an option.
For severe runny nose or nasal obstruction/congestion that does not respond to medications, your ENT specialist may consider additional office procedures or surgery appropriate to your situation.

Our sinuses not only help us breathe, they keep out potentially harmful dirt, allergens, and other agents in the air. ENT specialists treat allergies, deviated septum, rhinitis, sinusitis, sinus headaches and migraines, nasal obstruction and surgery, and more.
