MrsLee- here's some further 'scoop" on rhinitis (allergic and non-allergic). The word rhinitis refers to irritation of the nasal membranes from any source.
VASOMOTOR RHINITIS is chronic running nose (rhinitis) that is characterized by intermittent (coming and going) episodes of sneezing, watery nasal drainage (rhinorrhea), and blood vessel congestion of the nasal mucus membranes. There appears to be a hypersensitive response to stimuli such as a dry atmosphere, air pollutants, spicy foods, alcohol, strong emotions, and some medications. There is no infection or true allergy causing these symptoms.
ALLERGIC rhinitis is caused by real allergens such as trees, grass, weed pollens or mold...and this is what they call "seasonal" allergy or simply out hayfever.
If one is allergic to indoor allergens like pet dnader, indoor mold, or (ugh) insect droppings or dust mites, they like to call THIS kind of allergy "perennial" allergic rhinitis, as opposed to "seasonal".
Since allergies have been ruled out in your case you are stuck with non-allergic rhinitis which usually casues year round symptoms (you poor thing!!!!) especially nasal congestion or "stuffiness" and headaches. These kinds of reactions differ from allergic rhinitis because they do not produce a reaction in an individual's IMMUNE system.
. Generally, this is called irritant rhinitis, and is triggered by strong smells, pollution, particulate matter in the air, smoke or other irritants.
They call the rhinitis "vasomotor" if you have a runny nose, but not necessarily congestion, stuffiness or headache.
Nasocort is a very effective steroid nasal spray, and you need to take it regularly for it to work properly..... Interestingly, I have read in several med journals that regular exercise can also be helpful. Why, I cannot remember!
Hoping I didn't overwhelm you with too many rhinitis varients (and believe me there are more!)...and that all the above info helps a little.
