Hello, There are many causes of abdominal pain in children. Allow me to ask some questions, please: How long ago did the pain begin? Was there a fever at the onset? Has the fever continued? Did it start after an injury? Change in appetite; any nausea, vomiting, or diarrhea? Weight change? Change in activity level? What about his diet? Are there any foods or drinks that bring on the pain or make it go away? Is it constant or intermittent? Does it awaken him from sleep or stop him from play? Is his complaint associated with any activity? Does he localize the pain to a particular region of abdomen? Does anyone else at home complain of bodily pain? Is there pain anywhere else in his body? Is his entire body stiff? What does it feel like when you touch him? Is there any jerking of body? Wetting or soiling his pants? Falling to the floor? When he is no longer stiff will he speak to you and know where he is? I am wondering if the stiffness is seizure activity. But I do not know of any seizures associated with belly pain. I request that you answer these questions and then return to Healthcare Magic. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Arnold Zedd
