Hi..
Thanks for the query..
It seems that the symptoms of itchy nose,runny nose ,runny eyes and cough can be due to
ALLERGIC RHINITIS and it can be due to causes like
allergic reaction to irritants like pollen, animal danders, dust and mites and at times even certain trees and grasses..
Blocked ear can be due to fluid accumulation due to
post nasal drip..
I would suggest you to consult an Allergist and get evaluated and a thorough clinical evaluation and investigations like allergic tests like
Patch test, RAST test, food challenge test etc can help in diagnosis and treatment can be done accordingly..
The tests will help in ruling out the exact cause of the allergen and once you know the cause of the allergic reaction you can avid exposure to it to prevent allergy attack..
You can also take anti allergics like Levocetrizine, Allegra etc along with steroid nasal sprays to relieve the symptoms..
Use decongestant nasal sprays..
Do steam inhalations..
You can also be instilled an
Immunotherapy that will help in reducing the severity and frequency of allergic attack..
Hope this helps..
Regards.
