Cold in 3 yr old

3 year old girl with fever, cough and runny nose since few days. Her cough was very bad like barking cough and she was crying continously.
She had been to 3 clinics before but her symptoms did not subside.
I treated her with homeopathy ferrum phos, apis, ruta, senega, spongia tosta, chamomile and low dose CMV and epstein barr nosode. After 2 days she was totally fine.
