It seems you are coming down with an attack of upper respiratory tract
infection, hence the symptoms. I do hope you have no allergy. You may take a tablet of sinarest
or alerid cold and use flixonase or duonase nasal spray
. Take rest, have adequate sleep and take warm liquids like tea, soups etc. You should be alright with these and if not consult an ENT specialist
who will prescribe you with a short course of antibiotics.
