Cold running nose cough. To wheeze?

My son has cold cough wheezing and running nose from past 11 days because of that he was not eating at all but demanding water in every hour which is unusual for him.so we visited a pediatrician he suggested tminic asthalin syrup and nebulizer but we are not giving him any nabulising as my baby don't feel comfortable with it. now he is better.he is eating satisfactory and active enough but even after 11 days running nose appears mostly at morning and evening. I want to tell you that I stopped giving him asthalin syrup but tminic I m giving him 2 times a day. pls tell me the solution of that much long running nose problem. and also I want know from last 2 times his normal cold and running nose is turning into wheeze which is very painful for him and for us also. he get restless, don't sleeps so might and also don't like to eat anything. pls give me suggestins. it is so painful for us to see him like this and also I m very scared to imagine if he gets cold again and if it turns to wheeze
