Alex's stomach pain!

Well, it has been decided to run further tests on Alex's stomach.  Many of you know that for about 2 1/2-3 months, Alex has been complaining of her stomach hurting.  She has made many trips to the nurse at school and seen the doctor too.  She has as a doctor would call it, "functional abdominal pain".   The stomach is so hard to diagnose.  It could be nothing.  Although the pain is real she could out grow whatever is going on.  It could be the onset of Diabetes, food allergies, we just don't know.  All I do know was that she came in at 4 this morning in agony, threw up once and now she is fine.  This has been going on for so long now, that it is kind of normal.  She is missing school b/c we don't know if it is just a virus and we don't want her to spread it.  She HATES missing school.  She is now watching animal planet and fine.  She hasn't had much of an appetite in the last 2 months and has lost a little weight.   I am not sure what to pray for.  Do we want answers?  yes.  Alex has always been so healthy.  She is the girl that was born 5 weeks early and never had to spend a night in the NICU.  I remember the doctors being amazed at her strength back then.  Do we want the sonogram that she is having done next week to show nothing?  yes. Although that will not give us any answers, I don't want anything to be wrong.  As a parent, I have never felt so helpless. If it doesn't show anything, where do we go from there?  I hate hearing her say that her stomach hurts and I can do nothing for her, but say, "you'll be ok".  Almost 3 months later, she still isn't ok.  Please pray that we are able to make the right decisions and that God will reveal what is going on.   I truly appreciate your prayers and will keep you posted!!  We have had good news with Callum's ear in the last week, and good results with Liam's allergies.  I just pray that we can get Alex's stomach resolved and that we don't have any medical posts for a very long time!!!
