### output:

Hello. Thank you for asking at Chat Doctor. I went through your sons' history. I would like to know more details about him like - what kind of infection did he have? Does he have any other complaints apart from rashes? Do rashes cause him itching/excessive crying? Does he have any digestion related complains - constipation/frequent diarrhea? Does he have any other allergies? Does he have any family member with allergies? Do you give any medicines frequently to him (for fever, pain, etc.) apart from anti-allergic medicines? From your given history, I would like to make following suggestions for him:1. Were I treating him, I would prescribe him montelukast and levocetirizine for 1 week and review his response. I would suggest you to apply lotion like calamine over his itchy areas.2. An infection related rash can sometimes last for 4-6 weeks after infection. If he has persistent symptoms beyond 6 weeks, I would suggest him to investigate for food allergies, intestinal worms and other intestinal infections, urinary infections etc.3. Some Chat Doctor.
