My 8 year old has been suffering since birth with stomach issues. She has been on adult strength prepaid prescribed since she could eat and drink. She has fevers, headaches, stomach pain, hot flashes, she's afraid to eat but when she's hungry she can eat but then crystal in pain. Doctors can't give me any answers. She suffers when she eats. She gets diarrhea. Painful bloated stomach. What do I do? She has been tested for everything, and nothing. Should I leave her alone? What if something gets worse? Please help.
