Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that
severe sneezing along with pain in nose and breathlessness seems to be most probably due to
allergic reaction to some unknown allergen and the most common ones are pollen, animal danders, dust and mites and even certain trees and grasses..
I would suggest you to consult an Allergist and get evaluated and a thorough clinical evaluation and investigations like Allergic tests can help in diagnosis and treatment can be planned accordingly..
You can be advised to take anti allergics like
Allegra,
claritin, levocetrizine etc..
You can be advised to use decongestant nasal sprays to ease in breathing..
Once the allergen is ruled out try to eliminate it from your belonging area..
You can also be instilled an
Immunotherapy to reduce the severity and duration of allergic attack..
Hope this information helps..
Thanks and regards.
