Thanks for query.
It seems that you are having upper respiratory tract
infection, mostly viral.
Take some decongestant tablet like Diominic DA or Wikoryl.
If require put decongestant nasal drops like Otrivin
nasal drops in the nostril
You may go for nasal inhalation with Vicks or balm.
Within 2-3 days you will be alright.
Ok and bye.
