HI, thanks for using healthcare magic
Rhinosinusitis is inflammation of the nasal passages and sinuses
. It can be due to infection or allergies.
If your investigations indicate that it is not infective in origin then your symptoms may be provoked by an allergic stimulus.
You may want to consider having allergy
testing done, this would identify the allergen that is causing the symptoms and if this can be eliminated or reduced, it should result in an improvement of your symptoms.
Normally in addition to elimination of the allergen, the following medication is recommended: topical steroid
nasal sprays, antihistamines and decongestants (oral can be used for a long time but topical decongestants can only be used for 3 to 5 days at a time).
You can also try singulair
which is a mast cell
stabiliser and prevents the release of histamine in the blood stream.
I hope this helps
