I had given him homeopathic medicines.Later we went to his paeditrician and the doctor had diagonosed throat infection, but chest clear and had given him an antibiotic. By the day end his fever had also subsided, as such we did not give him antibiotic. Now the problem is even after 10 days his cough is not clearing up and he is spitting slightly greenish cough. Shall i give him the antibiotic? Pl help.
