daughter's stomach/esophagus pain

My daughter is 15 y.o. and has been having stomach pain for months and months. We have had every test imaginable and she just finished a round of antibiotics. I am awaiting a phone call from two doctors today after faxing and emailing them about my daughters continued suffering. I have researched and seen many other posts from parents who children are suffering from the same symptoms with no relief. I looked into Reliv as I had heard great things about them but discovered today that it is made up mostly of Soy which is not good for human consumption. Please watch the movie "Food, Inc." Soy is a multimillion dollar industry even though it is very bad for human health unless fermented. Anyway, I'm glad I looked into Reliv before ordering it today as I am desperate for a remedy for my daughter's pain. She is home from school yet again because of it. Her face constantly shows her pain. She is not the fun energetic child she used to be. It is so sad. If anybody out there reads this and has had the same experience and has gotten a remedy please contact me ASAP. Thanx!
