<s>[INST] Hello- My 6 year old son has been complaining of a tickle in his heart/chest area for 4 days. We went to the doctor and she thinks acid reflux... I don't think so. It is coming and going...he has no other symptoms and does not lose his breath etc... any ideas of what this might be in children? [/INST] I think you mentioned hiccups or just irritation in upper chest ? Hen it is probable that it could be GERD ( acid reflux ) though not very common in a six year old. I would give anti acid syrup like Zantac and an antispasmodic and observe. If there is nausea and vomiting an antiemetic could be given. YOu watch for any other symptoms and consult your doctor.
