Hi Dear, Welcome to HCM. Understanding your concern. As per your query your child has symptoms of cold and cough which is due to allergic reaction or due to repeated viral respiratory tract infections. Need not to worry. I would suggest you to take combination of antihistamine and antibiotic drugs . You should take antihistamine such as Benadryl or Chlorpheniramine along with Amoxicillin. Use vaporizers rub. Use room humidifiers as well to prevent any allergic reaction to child. Avoid hot, sharp, spicy food. You should give cough expectorants to child. Its better to avoid steroids and if you want to give it to child giv it for very short duration as it can cause dependency. Visit pulmonologist/ pediatrician once and get it examined if symptoms keeps on persisting. Start treatment after proper diagnosis. I would advise you to get your sinus x ray done and consult your physician to find proper diagnosis and then start treatment as per that. Hope your concern has been resolved. Get Well Soon. Best Wishes, Dr. Harry Maheshwari
