You probably might have caught the flu lah.... Have lots of
water and rest. Dun worry about your puffy face. It's just water
retention. Your "drainage system" is clogged for the moment so that
water circulation and removal is not so efficient for now, hence
your clogged nose ans puffy face. Once the blockage clears, your
nose should become clearer and face fuffiness reduced.
You may want to get "Clarinase" over the counter from most
pharmacies to help you expedite recovery....
