thanks for asking question.
as there is post nasal drip
, its mostly a diagnostic of sinus infection
and if you have recurrent sneezing and itching in nose and throat suggest allergic in origin. just avoid allergens like dust, fumes, very hot or very cold water, any eatables that precipitate attack. take some topical steroids Like Mometasone nasal spray
to decrease the post nasal drip and inflammation along with it take antihistaminics like tab levocetrizine or fexofenadin. this will solve your problem. thank you so much for using HCM
