Hi, Thanks for using HCM.Upper respiratory infection
are common in children below 5 years of age. If symptoms of URTI reduces in a week or 2 week duration and with or with out symptomatic treatment, you need not have to worry. If he gets worsening of symptoms or persistence of symptoms need to get examined by a doctor.
Swelling above umbilicus
could be a lipoma
or paraumbalical hernia. which can be diagnosed by examination and confirmation can be done on by ultrasound
examination.Depending on diagnosis management can be planned accordingly.
Hope this helps you.
