Hi, a few weeks ago at night my son (10)developed bad diareaha, like liquid. He was upset b/c he had a bout a week or so before..we could not pinpoint the reason. After sitting on the toilet for a long while..he came upstairs saying something terrible is wrong, almost crying, he played down and his body was clammy/sweaty to the touch and he has involuntary tremmors..holding his abdomen he said he had a terrible pain, we assumed was cramping. I called the pedi nurse in the am, she explained it was going around , I worried about food poisen, she said be sure he urinates several x a day, he was.. This pain stayed a few days again we thought cramping, but as the days go on every time after he eats and later in the day he still complains of pain. In the am he complains the mid band on his waist pants bother him. I want to call the dr and go in, are there any special test we should ask after palpating the area? I m becoming worried what really caused the involuntary tremmors in his lower body and all of a sudden clammyness was something inside..thanks
