Hi Doctor, My Son is having Cough with flem, vomiting at times, pain in stomach, runny nose with thick mucus for last 1 week. I consult a pediatrician and he told my son got viral Infection. He prescribed Resyl and one Expectorant cough syrup for 1 week. My son got better but still he cough at times and lil bit runny nose is there. Should i start with any Antibiotics, Doctor
