Helpless mom needs help and answers

[Lhigh]

My son is 8  years old and healthy, on saturday he started having pain below his belly button it has stayed consistant. At night it gets to a extreme. Its a throbbing pain. I have taken him to the ER twice. They have done a xray blood tests and a urine test all came out normal. They say his appendix is fine. I feel so hepless, my son is in pain and I cant hep him. Pain medicine dont work. He doesnt have the flu or a cold. I feel like the doctors just think he does. There is no other symptom just the pain.. Idk what to do.. please help

okay sometimes children do say they have a pain if they dont want to go somewhere its not unusual .So I would take him to the doctor for another examination.
