My kid ( 3.6 years)is having cough since January 2018, when stated schooling for nursery.I tried many allopathic & ayrvedic medicines.The cough was all over the day, after medication it occurs in each alternative day & when it starts it stays for 2 hours. It just suppressed the dough for some days,then cough returns.The doctors conformed it as allergic cough. No sinus issues. From last month onward i started homeopathic. The doctor conformed us nothing serious,it is a issue with weak immune system, the cough it will disappear. I am very worried.Anybody have any idea that how the homeopathic will work & how long the treatment requires ?
