Hello! The child has a rare cough, runny nose and coughs with a temperature of 37.6-38-37.5 for two days already, he's been sleeping poorly and crying constantly. Yesterday we called an ambulance, they took us away and said it was a virus and the throat is red, and prescribed the same medications as at home. Today, there's some mucus discharge, how long did you take to recover? Please tell me, I will be grateful ??
