<s>[INST] My 5 yo son has been experiencing transient stomach pain (around his belly button) for the last 3-4 weeks which lasts between 5 & 30mins. He complaints of being puffed out when running a short distance & has been quite irritable & cries easily. He woke up last night at 4am saying his stomach was sore & he thought he was going to vomit. No temperature. The pain lasted about 2 hours. The pain is worst when moving his tummy in & out and hurts more when palpated. It usually occurs fairly soon after eating. Any ideas on what it might be? [/INST] Hi...by what you quote this could be chronic pain abdomen. Most of the time we do not find a reason for it even after extensive investigations. I have a few questions and suggestions for you - Questions-1. How many months is he having the problem?2. Is there any family history of gall or kidney stones?3. Did he have urinary tract infection in the past?4. Anybody else in the family is having a similar problem?5. Does he have constipation? Suggestions-1.
