Runny nose, sneezing
, nasal discharge (usually white), cough are signs of an allergic process. Once the rhinitis
goes beyond control and affects the airways, you develop breathing difficulties as in asthma.
That the CBC is normal, suggests the eosinophil count
is also normal, that would exclude severe allergies.
However, house dust mite or fungal allergies are common at this time of the year.
I would suggest long-acting antihistamines like cetirzine 10mg (maximum twice daily) and/or a nasal spray
like Flixonase 2 sprays per nostril twice daily for 1 month and see the benefit.
If things worsen after you stop, please get a blood test
or skin prick test (must stop all antihistamines for at least 1 week if skin tests are required) to exclude allergic triggers.
Hope this helps.
