Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain the symptoms of
sneezing and cold like symptoms does not seems to be due to infection but it seems more to be due to
allergic reaction and it seems that there are some irritants in your sleeping place that are leading to sneezing..
I would suggest you to consult an Allergist and get evaluated and he can do a clinical examination and also advise you investigations like
Patch test, RAST test etc to rule out the exact cause of allergic reaction and preventing exposure to allergen can prevent the symptoms..
Common allergens are pollen, animal danders, dust, mold, certain grassses and trees can also be a cause..
As of now you can take anti allergics like Levocetrizine and
steroid nasal spray to relieve the symptoms..
Hope this information helps..
Thanks and regards.
