my son is suffering with a heavy cough and fever(with 102" f) continuously from last days visited doctors and medicate but fever still not into control. still it's showing 101 - 102 F. Doctors say that it's normal to not worry about using the gvn course of syrup and antibiotics. but why I don't even not going for the blood test because it causes any viral fever effect based on my son situation. I visited two doctors saying the same thing. what to do now.
