My daughter is eight years old now, but ever since she was about 4, she would say she didn t feel good, throw up one time, tremble a little, fall asleep, and wake up as if everything were okay. We took her to a GI specialist when she was about 7, and they didn t find anything. Things have improved, however, she still has these episodes without the throwing up. Tonight she said she didn t feel well. The front of her head was hurting. She also said she felt very nautious. She got a little shaky and is now finally sleeping. I m clueless.
