hi there, you seem to be suffering from coryza
or common cold
which is usually viral in origin and most of the time self-limiting. For symptomatic relief you can take over the counter anti-histaminics with anti-inflammatory combination and do lots of warm saline water gargling. You could take steam inhalations with euclyptus oil in it. Avoid chloraseptic
if it is not agreeing with you. Best remedy is complete bed rest
for a few days and you will be as good as new. Take care.
