My 1.4 year old child is having fever and occasional coughing. From yesterday night we have seen that his chest and back is very rough and he is having fever more than 100 farenhite. I have given him Tixylix and Salhexin syrup and Crocin in 6 hrs interval.Now we have consulted a local doctor and he had given vent pd and tixylix and clavam pd( amoxicilin and clauvanate acid combination). My question is what the reason for the rough surface in back and chest and should we continue giving salhexin and clavum or change salhexin to vent pd. Please suggest the medicines. He is having cough and cold problem from his birth and last month he had went thru congenital branchial sinus. Is there any relation with the surgery with this problem?
