Hi, thank you for writing on Healthcare Magic. I have gone through your query and understood your concerns. With this presentation, I think your child might be developing some complications of common cold which could be bronchitis or pneumonia. Management of these conditions require antibiotics. In my opinion, I would suggest you see a GP or Pediatrician for proper assessment and management. I hope that answers your query.
