Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that you are suffering from allergies to Environmental pollutants like dust, pollen, animal danders etc..
Other causes can be certain grasses and trees..
As you have taken nasal sprays and pills that seems to be anti allergics, I would like you to first of all consult an Allergist and get evaluated and a thorough clinicl evalutaion and allergic tests can help in diagnosis..
Once the cause of
allergy is ruled out, the best way to prevent the symptoms is to avoid exposure to allergen..
You can continue taking anti allergics like Levocetrizine,
Claritin etc..
You can use decongestant nasal sprays like Xyometazoline..
You can also do steam inhalations and use a humidifier in your room..
You can avoid exposure to dust and pollutants..
You can also be advised
Immunotherapy by Allergist and it will help in reducing the severity of symptoms and also reduce duration of the symptoms..
Hope this information helps..
Thanks and regards.
