He is often affected by cold and cough, it's severity case goes to wheezing. Then he cured by giving nebulization. We consulted doctor they told he is affected by allergic Cold. At 10:1 ratio of children affected by this type of cold ,so that he is easily affected by cold compared to other children.Doctors suggested to use inhalers for him. We didn't go for that one. Can you plz help me to recover this by using only medicines.
