It is unlikely that it will be possible to get rid of unpleasant symptoms quickly, but do not let it go by itself. Especially when a cold begins with a sore throat, because an elementary feeling of dryness in the throat can subsequently develop into a cough or even a sore throat. Each person has his own microflora and very often the same bacteria provoke the disease. To identify them, it is better, at the first signs of the disease, to do a pharyngeal culture at least once, to determine what exactly causes the malaise and to which drugs the sensitivity. This will help you determine which drugs are right for you and each time the treatment will go faster.
Unfortunately, the ARVI symptoms will not completely disappear in less than a week. It is during this time that antibodies against infection or a virus are produced. So everything, except for paracetamol or drugs based on it (teraflu, for example) does not make much sense.
