Girls we got sick ? First I had a cough, now my daughter coughs too. We went to the doctor and they prescribed us some medicine for the cough - Span, throat spray Golapro, candles Genferon Light. It seemed like the cough was going down, but on day five of the medication, the temperature rose ? Now the doctor prescribed an antibiotic Ospasmoks and Enteroshermine. On the second day, I give the antibiotic and it's still not gotten better. The cough became with phlegm (I'm very worried. I'm afraid that it might not go away and injections will be given ?)
