My 8 yr old daughter has been complaining of stomach pain for the last couple of months. Initially the doc had asked to control outside food especially bakery items and had also prescribed nexpro junior for a week. At that time she had shown some recovery, but again when she started complaining we took ultrasound of abdomen. As per the report there is a prominent well defined oval mesenteric node seen in periumbilical region of short axis 4-5 mm. Want to know, Is there any serious problem, if so what is the treatment and any changes to be brought in her diet?
