A. Mam this is the situation I can assure you that your child is having some allergy because I’ve seen that physically with a lot of people where they have severe cold but it’s usually associated with allergies if you consult an allergy expert and get their proper testing then you know Hotel allergies your child is suffering from and then you can start with the treatment accordingly either with the same doctor or you can go for immunotherapy or homoeopathy
