Hi ! Good afternoon. I am Dr Shareef answering your query. There could be very many reasons for the pain abdomen with vomiting in this age group starting from simple gastro enteritis to a surgical abdomen. This can be recognised only by a physical examination and related investigations if any apart from the fact that pediatric age group patients could very much vulnerable in proceeding fast to stage of dehydration needing hospitalisation. Therefore, I would suggest you to please take your child to either to the ER of a nearby hospital or to his usual pediatrician so that proper examination and management could be done to avoid any such complication. I hope this information would help you in discussing with your family physician/treating doctor in further management of your problem. Please do not hesitate to ask in case of any further doubts. Thanks for choosing health care magic to clear doubts on your health problems. Wishing you an early recovery. Dr Shareef.
