hello, i am 34 y.o, 172cm and 70kg. I m french but staying now in a village in India. i saw a doctor 2 days before for throat & ear infection. he gave me antibiotics treatment,ear is going better, but still is big infection in throat ( with pus), some fever & pain in back muscles. so, when i saw him today, he told me to finish first treatment (3days more with roxithromycin 150) and following this, five days with azithromycin 500...is it normal procedure?
