My DD 3 has been suffering with severe abdominal pain for the last 8 days. We have had her in hospital and all tests have come back negative. She is generally happy but uncomfortable with sudden attacks of severe pain that last about an hour. They are so bad she is ripping hair out. Urine negative, scan negative, no other symptoms other than occasional reflux. She will go from playing to suddenly not wanting to walk or play. Just lays down looking sad for hours. The severe pain usually happens at night. I don't know what to do
