question: Hello doctor, My son is 5 years old. He is dealing with continuous chest congestion and coughing with change in season. Doctor suggested Foracort 100 for two to three months with two shots in the morning and two at night after using nebulization Levolin 1.25 mg and Budecort 1 mg in the past for chest congestion. Will it affect his immunity? He eats healthy food with no junk at all, but still gets cough and congestion so frequently. Please suggest some medicine. Is it due to pollution? Or as he grow, will the things be better for him?
