My daughter is experiencing mid abdominal pain. so bad that she doubles over in pain. Along with it she has a fever of around 100 degrees feels like she has to have a bowel movement but its like she is constipated. When she finally does go it is diahrea. With some physical weakness. We have seen a doctor for this 4 times in the last 4 months and he keeps passing it on as acid reflux and tells me to give her pepcid. She is 12 years old.
