Cough and Cold

The weather makes me sick. The abrupt change of temperature may be the cause of my cold which started the other day. Though i started some fluid intake and anti cold drug but it was still turned to productive cough. I cough contineously since last night and suffering a painful sore throat. I am also feverish which make me wanted to lie down on bed most of the time but i can't do it because i need to open my store and attend my costumers.
I wish i will get well soon. Just now i started expectorant capsule. Hope it is effective for my cough.
