<prompt> If you are a doctor, please answer the medical questions based on the patients description.hello doctor... my son is 1yr 10 months old now.when he was 4 mnths it was observed havin TB, so we gave an ATT course of 6 mnths to him,after that his reports were ok. But since then he continuously develop fever,cold cough within a duration 0f 1 or 1 12 months. what may be the cause, my doctor is saying he is allergic reaction,he is suggesting to keep him on inhaler but i dont want to...please tell me wat i should do.  <response>: Welcome to the ChatDoctorI completely understand your concerns but dont worry. The most likely reason for sucChatDoctorplaints are recurrent viral infections which are usually self limiting and improve gradually over time. The frequency increases after tuberculosis due to low immunity. Allergic coughs are not usually associated with fever spikes. Use of inhaler therapy is purely guided by lung functions and clinical examination. So, I would recommend you the following measures to help him out:1. Maintain a proper record of signs and symptoms and response to treatment.2. You may check him for immunity by CBC3. Also go for pulmonary function test if he suffers from recurrent wheeze and coughs.4. For symptomatic treatment give Spy. Chlorpheniramine or Ben Chat Doctor. 5. Ensure a good healthy diet and plenty of fluids. Hopefully this will help you. Take care
