My daughter started complaining of severe abdominal pain and was very lethargic on Thursday. Thursday night she started throwing up. Friday she was the same. Saturday morning I took her to Care Now who tested her for the Flu, Mono, kidney infection and checked her blood and urine. All came back fine. Saturday night, I took her to a small hospital in our town and they checked for all the same things, told her it was a bad flu going around and sent her home crying and in pain. By Sunday night, her pain level was at a 10 and she could barely walk. I took her to Cook Chilrens Hospital in Fort Worth. They tested her blood, urine, did a CT Scan, Sonogram, Endoscopy, Colonoscopy and more series of blood test as well as tested her stool. She did not eat anything for six solid days. One day she felt fine and it looked like it was getting better, the next day, without pain meds and nausea medicine, she got pale immediately, became lethargic and could barely speak at all. I thought she was going to die. This happened twice this week. Yesterday when she had the colonoscopy and edoscopy, she felt a pain level of zero for the first time and they said since all test came back fine and she seemed to be getting better, she would go home today. At 4 am the pain came back and now the nausea came back. The doctors have said that some times you just can't tell what causes pain and she may have to learn to live with it. This was a normal, healthy happy go lucky child a week and a half ago who had never been sick in her life. About two months ago, she developed lines on her back that look like scars, though she has never scratched her back on anything. Someone told me a friend of a friend child had the same thing and it was a rare blood disease. The doctors at this hospital don't look more than 25 years old and don't have the years of experience of a doctor who has ran across rare things. Please help me, we don't know what else to do. Celiac test still has not came back but if it is not that, what else could it be?
